The Indian Holly Fern - Beauty In Simplicity


Poking around one of my favorite streams in a wood, I saw a rather common fern for what seemed like the first time. Sure, I had noticed it before, but this time was different for I stopped long enough for a closer look and to be delighted by what I saw. Early plant explorers surely knew such pleasures. I imagine them hardly disembarked before stopping to study new finds and collect samples.

Karl Ludwig von Blume (1796-1862) was one of them. A German-Dutch botanist, he spent much of his life in southern Asia, especially in what is modern Indonesia. At the time, most of the archipelago was a Dutch colony. What a botanical treasure-trove he found.

Blume named a genus of ferns, Arachniodes (pronounced a-rak-nee-OH-dees), meaning "spider-like." The name was suggested, of course, by the growth habit of the plant. There are over 100 Asian species within the genus, and about 140 New World species.

A. simplicior (pronounced sim-PLIK-ee-or) is arguably the most beautiful. Common names include East Indian Holly Fern, Indian Holly Fern, Simplicior Fern and Shield Fern. Simplicior means "simpler", and it is in comparison with many of the other species which appear quite intricate. Its beauty is in its simplicity. Glossy evergreen fronds and pinnules are long and arching with light green variegation extending their lengths. It grows 12 inches to 24 inches high and may spread to 30 inches.

Indian Holly fern performs well in USDA climate zones 7 to 10 in partial shade. It prefers consistently moist soil, but not wet. Space large container-grown Indian Holly ferns 24 inches to 30 inches apart. Smaller ones can be planted closer together. Recommended pH is 6.5 to 7.5.

Such planting sites as those I mentioned shouldn't require cultivation. However, it's always wise to take a soil sample to your nearest Cooperative Extension Service office for analysis. You'll pay a nominal fee, and receive results within a couple of weeks. Follow instructions. I have found that ferns usually benefit from a top-dressing of compost and occasional feeding with diluted fish emulsion.

Shade gardens, fern collections, woodlands, moist stream banks and Asian gardens are perfect for the Indian Holly fern. Because it is relatively small, compact and evergreen, it also makes a fine house plant. It is deer-resistant. Indian Holly fern would make any plant explorer or garden visitor stop in his tracks for a closer look.

"Who can fear the winter stern while still there grows the Christmas fern."

Christmas Fern - Polystichum acrostichoides
The Christmas Fern - Polystichum acrostichoides

"When frost has clad the dripping cliffs
With fluted columns, crystal clear,
And million-flaked the feathery snow
Has shrouded close the dying year;
Beside the rock, where'er we turn,
Behold, there waves the Christmas fern.

No shivering frond that shuns the blast
Sways on its slender chaffy stem;
Full-veined and lusty green it stands,
Of all the wintry woods the gem.
Our spirits rise when we discern
The pennons of the Christmas fern.

With holly and the running pine
Then let its fronds in wreaths appear,
'Tis summer's fairest tribute given.
To grace our merry Yuletide cheer.
Ah, who can fear the winter stern
While still there grows the Christmas fern."
                                                  -W. N. Clute

People of science are often people of art. How can one delve into the wonders of creation without being astonished by the order and beauty? Willard Nelson Clute (1769-1850) was one of them. He was born in the village of Painted Post, Steuben County, New York. The name of the village comes from a painted totem that early explorers found at a river junction. The rivers, creeks and mountains nearby must have inspired his love of nature. He pursued his passion. Clute founded the American Fern Society in 1893. In 1928, he became professor of botany at Butler University, Indianapolis, and curator of the botanical garden. He authored over a dozen botanical books, some of which his wife, Ida, illustrated.

In Our ferns in their haunts: a guide to all the native species, Clute waxed poetic about the Christmas fern. Who could resist? As he noted, "To the hunter, the trapper and the rambler in the winter woods, the Christmas fern (Polystichum acrostichoides) is a familiar species. In summer it is not especially noticeable, but in the snowbound season, the cheerful, fresh-looking fronds are sure to attract the eye."

They did attract the eye, and were extensively harvested for Christmas greenery arrangements. Apparently all the collecting did little to diminish the numbers of the Christmas fern. It is widely distributed throughout its native range, from Quebec to north Florida and to eastern Texas. Because it is so robust, gardeners find it to be easy to grow.

Its botanical name, Polystichum acrostichoides (pronounced pol-IS-tick-um ak-ruh-stik-OY-deez), refers to the many rows of spores, and the fact that it reminded someone of another genus of ferns, Acrostichum. The seldom-used name, Nephrodium acrostichoides, is synonymous.

Christmas fern is hardy from USDA climate zone 3 to 9. It prefers well-drained, humusy soil like you'd find above creek banks and on woodland floors. Shady locations under hardwood trees are best, so it's an excellent choice for shade gardening. Soil pH may range from 5.6 to 7.5. Once established, it is somewhat drought tolerant and should be considered for xeriscaping. Being a fern, it is deer resistant.

I can't imagine why tilling such a site would be necessary. It's always good to take a soil sample to your nearby Cooperative Extension Service for analysis. Follow the recommendations.

Christmas ferns grow up to 24 inches high and 12 inches to 18 inches across. Dig planting holes about 12 inches apart. The holes should be no deeper than that of the rootballs. Water the plants in their pots, then plant them, watering more as you go. When planted, the tops of the rootballs should be visible; do not bury them under soil.

If you haven't already come to appreciate the beauty of Christmas ferns, I'm sure you will. Good cheer!

Japanese Painted Fern - Like Michinoku Cloth


Michinoku no
Shinobu moji-zuri
  Tare yue ni
Midare-some nishi
Ware naranaku ni.

AH! why does love distract my thoughts,
  Disordering my will!
I'm like the pattern on the cloth
  Of Michinoku hill,—
  All in confusion still.

-Kawara no Sadaijin (822 - 895)

Shinobu mojizuri is an ancient dyeing process, probably originating from Michinoku region in Japan, in which plants are pressed and rubbed into silk cloth creating an intricate pattern. The poet's simile expresses well the indelible, painful impression that love makes on the heart.

It occurs to me that the intricate pattern and shades of Japanese Painted Fern (Athyrium niponicum var. pictum) must resemble a Michinoku print. Emerging fronds are metallic gray with reddish to bluish blush. Mature fronds hold their color well and contrast nicely with the emerging ones. This fern forms very attractive clumps from 12 inches to 18 inches in height, and as wide.

For its beauty and adaptability, the fern was named Perennial Plant of the Year winner for 2004 by the Perennial Plant Association. Many gardeners find it irresistable.

Japanese Painted Fern goes dormant in winter, nevertheless it is reliably cold hardy in USDA climate zones 4 to 9. It performs best in partial shade to full shade, however, coloration is best in light shade. Some gardeners report success planting in full sun, but growers in hot climates should definitely provide adequate shade. Slightly moist soil is essential, though care must be taken to avoid over-watering. Japanese Painted Fern doesn't like soggy soil. Recommended pH is 6.1 to 7.5.

You'll be pleased to know that Japanese Painted Fern has no serious insect or disease problems, and it's deer resistant.

Before planting, take a soil sample to your local Cooperative Extension Service office for testing.  The results will specify any necessary soil amendments.

Prepare the planting bed by cultivating at least 10 inches deep, removing all traces of weeds. Compost may be incorporated into the soil.  Incorporate 10-10-10 fertilizer at a rate of no more 2 lbs. per 100 square feet into the top 4 inches to 6 inches of soil. Avoid synthetic fertilizers contacting any part of your plants.

Space the plants 18 inches to 24 inches apart. Small plants may be planted closer together. Dig planting holes into the cultivated soil a little less deep than the depth of the growing container.  Water the plants in the pots, then drain.  Place the ferns into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1 inch deep.

Shade gardeners will love Japanese Painted Ferns. Of course, they should be included in Japanese gardens and in fern collections. Their beauty is irresistible.

Here is another English translation of Kawara no Sadaijin's poem, number 14 of A Hundred Verses from Old Japan (The Hyakunin-isshu), tr. by William N. Porter, [1909].

Like the printed leaves of ferns
On Michinoku cloth,
Who has imposed on me
This affliction, but you.
But I can’t resist it.
-Kawara no Sadaijin (822 - 895)

Life Lessons From Silene


Sources that I've researched indicate that the genus, Silene (pronounced sy-LEE-nee), aka Lychnis, was named by Carl Linnaeus in 1753, probably with the mythical and not too unbelievable character Silenus in mind.

Lewd Silenus, tutor of Dionysus, satyr and drunk in bad company with a Cyclops, could not get enough of wine. Yet, he was known for his occasional wisdom, loosened by drink. He was an imaginary embodiment of these sayings:

In vino veritas; En oino álétheia (in wine there is truth).
In goes wine, out comes a secret.
In wine there is truth, in water there is health.

Euripides figured him like this, exchanging with ODYSSEUS:

SILENUS
...Let me have a single cup of that (wine) and I would turn madman,
giving in exchange for it the flocks of every Cyclops
and then throwing myself into the sea from the Leucadian rock,
once I have been well drunk and smoothed out my wrinkled brow.
For if a man rejoice not in his drinking, he is mad;...

...and there is dancing withal, and oblivion of woe.
Shall not I then purchase so rare a drink,
bidding the senseless Cyclops and his central eye go hang?
Euripides, The Cyclops (420BC)

Apparently, Silenus had had too much of water.

I've often wondered what goes on in the minds of plant taxonomists when they're bestowing names. Unfortunately, few have told. We know, however, that certain plant characteristics are often the bases for botanical names.

Silene is not known for medicinal qualities, nor is it associated with wine and intoxication. Some species have burgundy-colored flowers, but not enough of them to suggest the name. Many species of Silene have sticky parts, so are commonly known as Catchfly. Another common name, shared with other plants, is Bachelor's Button. Perhaps one holds a clue.

Well before the Victorians made much of the language of flowers, plants were steeped in symbolism. Daisies, for example, symbolized innocence. White lilies symbolized virginity. Red roses symbolized love. Ivy symbolized marital fidelity. Catchfly symbolized a snare. Perhaps that thought prompted Linnaeus to bestow the name.

Being the son of a Lutheran minister and amateur botanist, Carl Linnaeus was well-acquainted with Scripture. His father, Nils, probably taught him life lessons drawn from both.

No doubt Nils also warned him from the Bible as he left for University.

Take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and that day come upon you unawares. (Luke 21:34)

Let us walk honestly, as in the day; not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying. (Romans 13:13)

Surfeiting, drunkenness, rioting, chambering, wantonness, strife, envying and cares take their toll. Silenus, entrapped by greedy King Midas and wine, burst out, “Oh, wretched ephemeral race … why do you compel me to tell you what it would be most expedient for you not to hear? What is best of all is utterly beyond your reach: not to be born, not to be, to be nothing. But the second best for you is—to die soon.

Having been well-trained in Latin, Greek, Hebrew, theology, mathematics and botany, it's not much of a stretch to speculate that Linnaeus reflected on Catchfly and named it after tragic Silenus. Perhaps he even had a bit of personal experience from university life to draw upon.

Silene is a genus of about 700 species, distributed throughout the northern hemisphere. Some were formerly included in the Lychnis genus. Fewer than three dozen species are commercially available. Bloom time is generally from late spring to early summer. Most thrive in USDA climate zones 4 through 9. Average garden soil with pH ranging from 6.1 to 7.8 is fine. Drought-tolerance varies by species. Deer do not care to eat Silene.

Perennial borders, butterfly gardens, hummingbird gardens should include Silene. Flowers are good for cutting, too. Theme gardens emphasizing popular Victorian plants, the language of flowers, myth and legend would be perfect for Silene.

If you would like to grow Silene, choose a site in full sun to partial shade. Take a soil sample to your local Cooperative Extension Service office for analysis. You will pay a small fee. If your soil is not friable, cultivate to a depth of 8 inches. Add fertilizer and other amendments as recommended. Remove all traces of weeds.

Water the plants in their pots. Allow them to drain. With a garden trowel, dig holes twice as large as the pots. Space the plants about 12 inches apart. (Larger growing species can be planted farther apart.) Remove the plants from their containers, add water to the planting hole, fill in around (not on top of) the root balls with native soil. Water again. A light top-dressing of mulch may help to retain moisture and discourage weeds until your plants are established.

Silene, especially S. coronaria 'Gardener's World' with it's white foliage and striking red blooms, will certainly captivate your garden visitors. While you have their attention, instruct them in life lessons drawn from plants.

Solve The Mystery With Gromwell In Your Garden




The turf under the oak still retained the vague shape of Domville's body, but already the grasses were rising again. Cadfael prowled the pathway with his eyes on the ground, penetrated into the trees on both sides, and found nothing. It was a sudden shaft of sunlight through the branches, filtering through thick underbrush, that finally located for him what he sought, by picking out the glitter of the gold fringe that bordered the cape of the capuchon. It had been flung from its wearer's head when he was thrown, and buried itself in a clump of bushes three yards from the path, its fashionable twisted arrangement making it all too easy to dislodge in such a shock. Cadfael hauled it out. The turban-like folds had been well wound, it was still a compact cap, with one draped edge left to swing gracefully to a shoulder. And in the dark crimson folds a cluster of bright blue shone. Somewhere in his nocturnal ride Huon de Domville had added to his adornments a little bunch of frail, straight stems bearing long, fine green leaves and starry flowers of a heavenly blue, even now, when they had lain all day neglected. Cadfael drew the posy out of the folds, and marveled at it, for though it had commoner cousins, this plant was a rarity.

He knew it well, though it was seldom to be found even in the shady places in Wales where he had occasionally seen it. He knew of no place here in England where it had ever, to his knowledge, been discovered. When he wanted seed to make powders or infusions against colic or stone, he had to be content with the poor relatives of this rarity. Now what, he wondered, viewing its very late and now somewhat jaded flowers, is a bunch of the blue creeping gromwell doing in these parts? Certainly Domville had not had it when he left the abbey.

- Ellis Peters, The Leper of St. Giles, 1995

Just so did creeping gromwell provide the clue that would lead Brother Cadfael to solve the mystery of the murder of Huon de Domville. Being an herbalist, Cadfael noticed the posy and that it was out of place. Certainly, you understand because, as a gardener, you notice plants before you see much else.

But there is another mystery. What was the plant that Brother Cadfael spied? Culpeper noted the long-established medicinal value of gromwell in his Complete Herbal. Cadfael was drawn into this mystery in the first place because he was out and about looking to restore his supply of herbs. Was it a Lithospermum or a Lithodora? We may never know which; besides Cadfael is a fictitious character.

The Brother Cadfael Chronicles are set between the years 1135 and 1150. But the botanical name, Lithospermum, wasn't bestowed until around 1750 or so by Linnaeus. The genus, Lithodora, was described and separated from Lithospermum around 1844. Both have been commonly called "gromwell", in some form. But we do know that the flowers of Cadfael's gromwell were "heavenly blue", so that might help to narrow it down for you plant sleuths.

Of the two genera, Lithodora is more important horticulturally, so I'll focus on that. But I must note at this point that some of the plants within the genera are still called Lithospermum synonymously.

Lithodora (pronounced "lith-o-DOR-ah") means "stone gift", but there seems to be no record why it was named so. The stone might refer to the hard, nut-like seed the plant produces, but it might as well refer to the topography or soil type of some native habitat. Lithodora diffusa, for example, is native to southern Europe (Spain and Portugal) and a couple of areas near the southern Mediterranean.

Most species grow fewer than 8 inches in height, spreading perhaps to 18 inches. Foliage is lanceolate or linear, resembling rosemary but with hairy surfaces. Flower colors range from blue to white. (Lithospermum flowers are often yellow.) They tend to be drought-tolerant, making them ideal for xeriscaping. Acid soil is usually preferred. They aren't particularly cold hardy or heat tolerant, usually doing best in USDA climate zones 5 or 6 through 7 or 8.

Lithodora diffusa thrives in a broader climate range, usually from 5 through 9, which undoubtedly contributes to its greater popularity. Flowers appear in late spring and summer. It requires well-drained soil in full sun to partial shade. Soil pH should range between 5.6 to 6.5. Lithodora is deer resistant.

When you've chosen your planting site, take a soil sample to your nearby Cooperative Extension Service office for analysis.  Follow soil test recommendations, making any amendments as needed. Remove all traces of weeds. Apply an appropriate herbicide. I prefer glyphosate. If your soil is not friable, cultivate to 8 inches deep. Water your plants in the pot before installing. Space them 12 inches to 15 inches apart. Surrounding soil should come to the top level of the root ball; don't bury it. Water again after planting.

Lithodora diffusa is great for perennial borders, ground cover, containers, hanging baskets, herb gardens, and perhaps as a lawn substitute if foot-traffic is light. It's also ideal for tucking into stone walls. Consider planting a theme garden; perhaps a medieval garden, medicinal garden, or a literary garden to celebrate plants made famous in poetry and prose. If you are looking for a plant that will do all that, and if you garden in an appropriate climate zone, plant Lithodora. Your mystery is solved.

The Secret Is Oregano


ANDY - That certainly is delicious spaghetti, Mrs. Sprague, especially that sauce of yours.

MRS. SPRAGUE - Oh, thank you, Andrew. It's something of a secret recipe handed down through five generations of the Sprague family.

ANDY - Oh, a secret. Oh, well, whatever it is in there it certainly is tantalizing.

MRS. SPRAGUE - I really shouldn't tell you, Andrew, but it's a Greek spice called oregano.

ANDY - Oh, well, who in the world would ever think of putting oregano in a sauce?

HOWARD - That's what makes it a secret recipe, Andy.

-The Andy Griffith Show, Dinner At Eight, Episode 206

With Aunt Bee and Opie out of town, Goober stops by Andy's house to keep him company and to fix a spaghetti dinner, seasoned with a secret ingredient: oregano. Half-way through dinner, Goober remembers that he forgot to give Andy two messages, but can't remember what they were. One was from Howard Sprague, the other from Helen Crump. Dimly recalling, he sends Andy to Howard's for another dinner. Surprised by his visit, the Spragues put dinner back on the table and Andy is served spaghetti again. But Goober got it wrong. Afterward, Andy gets an angry call from Helen that he's one hour late for dinner. Again, it's spaghetti with a secret ingredient: oregano.

Popular since ancient times, oregano is no secret. It's a perennial herb, native to the Mediterranean region, with various species and subspecies indigenous to Kyrgyzstan, Italy and Greece, Crete and Turkey, and Syria. The most popular is Origanum vulgare, pronounced or-RI-gan-um vul-GAIR-ee. Oregano is commonly used, not only in spaghetti sauces, but in cuisines typical of most Mediterranean countries. Flavors vary somewhat by species and quality. Generally, oregano is more flavorful when dried than fresh.

Hippocrates is quoted as saying, "Let your food be your medicine, and your medicine be your food." It shouldn't come as a suprise that oregano has been valued as a medicinal herb. Hippocrates, himself, valued it as an antiseptic. Perhaps this is the reason that oregano was originally used as a food additive. It combats Listeria monocytogenes, a food-borne pathogen associated with milk, cheese, raw meats and even raw vegetables. Hippocrates wouldn't have known about Listeria, but the ancients certainly observed that some herbs helped to preserve foods and made them safer to eat. It's no wonder that the tastes of foods and associated herbs should become so inextricably linked.

Oregano has also been used to treat sore throats, stomach ailments and bronchial problems. As a poultice, it is said to relieve muscle aches and sprains. It's also known to be a powerful antioxidant.

Oregano grows as a low, sometimes creeping herb. Mature height is 6 inches to 12 inches, and spreads up to 18 inches. Showy pinkish-purple flowers appear mid-summer to early fall. It grows quickly and thrives in sun, though it appreciates afternoon shade in hot climates. It is drought tolerant, deer and rabbit resistant and tolerates foot traffic. Oregano thrives in USDA climate zones 4 to 9. It tolerates a wide variety of soil types with pH ranging from 6.1 to 8.5.

Before planting, test your soil. Your nearby Cooperative Extension Service can help you for a nominal fee. Follow the recommendations from the test results. If your soil is not friable, cultivate it 8 inches to 10 inches deep. Add amendments. Space the plants from 12 inches to 18 inches apart.

Oregano is excellent for container gardens, fragrance gardens, kitchen gardens and medicinal gardens, and as a ground cover. Golden oregano is one of the most attractive. If you enjoy watching butterflies, oregano will attract them.

Here is a recipe for pasta sauce I think you'll enjoy. The secret, of course, is oregano.

Ingredients  

    1/3 cup extra virgin olive oil
    3 garlic cloves, minced
    5 green bell peppers, cut into 1/4 inch strips
    1 small onion, sliced into 1/4 inch rings
    8 ounces black olives, sliced
    1/2 teaspoon dried cayenne pepper flakes
    1 cup dry white wine
    32 ounces low-sodium (salt) tomato juice
    1 teaspoon dried basil
    1/2 teaspoon dried oregano
    2 tablespoons honey
    1 teaspoon anchovy paste
    Salt and black pepper to taste
    1 tablespoon chopped fresh parsley

Directions

    In a large skillet, heat the oil on medium-high, add the garlic, and cook, stirring, until the garlic begins to turn golden.  Add the peppers and onion and cook until they are soft and browning at the edges. Add the olives and crushed cayenne pepper. Pour in the wine, stir and cook for 1 minute.
    Add the tomato juice, basil, oregano, honey, salt and pepper. Stir in anchovy paste. Heat to boiling, then reduce heat to medium. Cook until the liquid is reduced and the sauce is thickened. Stir in fresh parsley. Serve with pasta.

River Lily, Spider Lily, Swamp Lily, Poison Bulb


River Lily, Spider Lily, Swamp Lily, Poison Bulb are common names for species in the genus, Crinum (pronounced KRY-num).  There are about 180 of them found around the globe in tropical and subtropical habitats.  Yes, especially near swamps and rivers.

Crinums grow from bulbs which, like so many ornamental plants, are poisonous if ingested.  Leaves, usually strap-like, may be evergreen or deciduous, depending upon the species.  Clusters of handsome flowers, often fragrant, are produced on long, leafless stems throughout summer.  Leaves and flowers may also be toxic, so keep your lips off.  Consequently, crinums are deer resistant.

Crinum is a member of the Amaryllidaceae, which includes Amaryllis, Clivia, Hippeastrum, Leucojum and Lycoris.  The family resemblance is obvious.  In fact, you might say that Amaryllis and Crinum are "kissing cousins", having been bred to produce an intergeneric hybrid, x Amarcrinum.

Crinums may be cold hardy from USDA climate zone 7 through 11, depending upon the species.  Those who live in cooler regions can grow the smaller species successfully in containers with winter protection.

If planting in the garden, select a site in full sun to partial shade.  Obviously, crinums perform best in moist soils similar to their native habitats.  Generally they prefer a great deal of water.  Some species such as Crinum thaianum are aquatic and often used in aquariums.  Some require the soil to dry between watering to avoid rot.  But I know from personal experience that many are quite drought-tolerant.

Soil pH may be acidic to neutral.  Exact requirements differ by species.  The best way to determine if the pH is within that range and contains the proper nutrients is to have the soil tested. Your local Cooperative Agricultural Extension Service can help you.  You can collect the soil sample yourself.  For a nominal fee, they will send your soil sample to a laboratory for analysis.  Be sure to call the Extension office for instructions.

Cultivate the soil to the depth of 12".  Add plenty of well-rotted compost.  Remove weeds.  Soil test results may recommend other soil amendments.  Bone meal is especially beneficial for bulbs.  If you use synthetic fertilizer, allow at least a week before planting so it can be incorporated into the soil by rain or irrigation and not burn the bulbs.

Planting depth and spacing vary by species and bulb size.

Crinums are stately additions to the garden, lending a bold tropical appearance to the landscape.  Sweet scented species are perfect for fragrance gardens.

Growing crinums in containers is not much different than in the garden.  Use the finest potting soil; cheap soil will give poor results.  The best potting soils will be light-weight, peat-based with added materials to enhance plant growth.  Select containers that will accommodate the bulbs and any other suitable companion plants.  All companion plants should have similar soil and moisture requirements.  Because container gardens can dry quickly, take steps to keep the pots properly watered.  Adding moisture retentive gel to the soil can be beneficial.  Larger containers are not as susceptible to drying.  Tipping over can also be a problem with small containers.

When bloom time is over, let the foliage remain to build reserves in the bulbs for the next growing season.  You may remove the foliage from deciduous species when it has turned yellow.  Continue to irrigate as needed.  Deciduous species will need considerably less water, if any, when foliage has fallen.

The following are a few of the most popular crinums:

Crinum 'Ellen Bosanquet' - Fuschia, trumpet-shaped flowers on 20" to 30" plants.  Evergreen foliage.  Climate zones 6 - 10.  pH 6.1 - 7.5.  Drought tolerant.

Crinum 'Ollene' - Fragrant, white, trumpet-shaped flowers on 18" to 24" plants.  Evergreen foliage.  Climate zones 6 - 10.  pH 6.1 - 7.5.  Consistently moist soil.

Crinum 'Walter Flory' - Fragrant, pink, trumpet-shaped flowers on 24" to 36" plants.  Evergreen foliage.  Climate zones 7b - 11.  pH 6.1 - 7.5.  Consistently moist soil.

Crinum 'Mrs. James Hendry' - Fragrant, pale pink, trumpet-shaped flowers on 36" to 48" plants.  Evergreen foliage.  Climate zones 7b - 11.  pH 6.1 - 7.5.  Consistently moist soil.

Crinum 'Stars and Stripes' - Red and white striped, star-shaped flowers on 18" to 24" plants.  Evergreen foliage.  Climate zones 7b - 10.  pH 6.1 - 7.5.  Consistently moist soil.

Crinum 'Hannibal's Dwarf' - Pink, star-shaped blooms on 12" to 18" plants.  Evergreen foliage.  Climate zones 7b - 10.  pH 6.1 - 7.5.  Consistently moist soil.

Crinum amabile - Pink, spider-shaped flowers on 36" plants.  Evergreen foliage.  Climate zones 8 - 11.  pH 6.6 - 7.5.  Very high moisture needs.  Suitable for bog and water gardens.

Crinum americanum - White, spider-shaped flowers on 24" plants.  Evergreen foliage.  Climate zones 7 - 10.  pH 5.6 - 7.5.  Very high moisture needs.  Suitable for bog and water gardens.

Crinum asiaticum - Fragrant, white, spider-shaped flowers on 48" plants.  Evergreen foliage.  Climate zones 9 - 11.  pH 6.1 - 7.8.  Consistently moist soil.

Crinum pedunculatum - Fragrant, white, spider-shaped flowers on 60" to 96" plants.  It's a whopper!  Evergreen foliage.  Climate zones 7b - 11.  pH 6.1 - 7.5.  Consistently moist soil.

Crinum x powellii - White or pink trumpet-shaped flowers on 24" plants.  Evergreen foliage.  Climate zones 8 - 11.  pH 6.1 - 7.5.  Average water needs.  Avoid over-watering.

X Amarcrinum memoria-corsii - Pink trumpet-shaped flowers on 24" to 36" plants.  Deciduous foliage.  Climate zones 7b - 10.  Average water needs.  Avoid over-watering.

This should provide you with a good over-view of Crinum.  You'll love the dramatic appearance they lend to your garden or sunroom.

Thyme It Is A Precious Thing




Come all ye maidens young and fair
And you that are blooming in your prime
Always beware and keep your garden fair
Let no man steal away your thyme.

For thyme it is a precious thing
And thyme brings all things to my mind.
Thyme with all its flavours, along with all its joys
Thyme, brings all things to my mind.

Once I had a bunch of thyme.
I thought it never would decay.
Then came a lusty sailor
Who chanced to pass my way
And stole my bunch of thyme away.

The sailor gave to me a rose.
A rose that never would decay.
He gave it to me to keep me reminded
Of when he stole my thyme away.


Those lines from an old Irish song, A Bunch Of Thyme, remind us that herbs mean more to us than we often realize.  In the song, the herb symbolizes virginity and chastity.  In the language of flowers, thyme symbolizes courage, vigor and strength.  All are important virtues to be guarded.  It seems that herbs strike some deep chords within us that resonate when we experience them, especially by taste or smell.  It's certainly so with thyme.  I have a small jar of it beside me now.

Thymus (pronounced TY-muss) is a genus of about 350 perennials native to warmer regions of Europe, Africa and Asia in the Mediterranean region.  It belongs to the Lamiaceae or mint family.

Thymus has been highly valued and used by western civilizations since the ancient Greeks as incense, fumigation, anti-depressant, pest repellant (though powerless against lusty sailors), vermifuge, antiseptic, antifungal agent, mouthwash, treatment for skin infections and bronchial disorders, and flavoring.  Hippocrates is quoted as instructing, "Let your food be your medicine, and your medicine be your food."  Thyme is a healthful flavoring, indeed.  It contains antioxidants, is rich in potassium, iron, calcium, manganese, magnesium, and selenium, B-complex vitamins, beta carotene, vitamin A, vitamin K, vitamin E, vitamin C and folic acid.

Thyme has small, soft, aromatic leaves.  Diminutive lavender flowers are produced throughout the growing season. 

Most species are low-growing and spreading, so they are wonderful as ground covers planted near stepping stones.  Thyme tolerates some foot traffic, so can used as a lawn substitute.  Herb gardens, fragrance gardens, hummingbird and butterfly gardens are not complete without thyme.  Bees produce excellent honey from thyme.  Thyme is drought-tolerant, deer and rabbit resistant.

Where ever you plant it, you'll find yourself looking for recipes that include thyme.  It can be used in recipes fresh or dry, and is marvelous as an ingredient in aromatic cooking oils.

Thyme is generally hardy in USDA climate zones 4 through 8 or 10, requires full sun and well-drained soils with pH ranging from 6.5 to 8.5.  Take a soil sample to your nearest Cooperative Extension Service Office for proper analysis.

Prepare the planting bed by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.  Compost may be incorporated into the soil. 

Space the plants 8" to 24" apart, depending upon the species. Dig planting holes into the cultivated soil a little less deep than the depth of the growing container.  Water the plants in the pots, then drain.  Place the plants into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1" deep.

Plant thyme with other plants having similar cultural requirements.  Fertilize sparingly with organic fertilizer and allow soil to dry between watering.  The greatest cause of failure is over-watering.  Thyme is definitely a low-maintenance plant.

Thyme, "with all its flavours, along with all its joys", pleases the senses while it improves health and enhances the landscape.  "Keep your garden fair and let no man steal away your thyme."

Give Me Pearlwort


"Some people are flower lovers.
I'm a weed lover," wrote English poet Norman Nicholson.


Weeds don't need planting in well-drained soil;
They don't ask for fertilizer or bits of rag to scare away birds.
They come without invitation;
And they don't take the hint when you want them to go.
Weeds are nobody's guests;
More like squatters.

Coltsfoot laying claim to every new-dug clump of clay;
Pearlwort scraping up a living from a ha'porth of mortar;
Dandelions you daren't pick or you know what will happen;
Sour docks that make a first-rate poultice for nettle-stings;
And flat-foot plantain in the back street,
gathering more dust than the dustmen.

...You can keep your flowers.
Give me weeds!

Nicholson's argument is compelling.  Just yesterday I spied a tidy clump of pearlwort growing beside an asphalt walk as a fellow was shoving a lawn mower over the grass around it.  It occurred to me that he might be better off if he planted his entire yard in pearlwort.

Pearlwort is of the genus Sagina which includes about 90 species native to Europe and North America.  It's a member of the Caryophyllaceae family which includes dianthus, carnations and campions.

Though most of the pearlworts are attractive, Sagina subulata is the one most commonly grown as an ornamental.  The green form is also known as Irish Moss while the yellow cultivar, Sagina subulata 'Aurea', is often called Scotch Moss.  Neither are native only to Ireland or Scotland.

Pearlwort is most often grown as a perennial, evergreen ground cover.  Mature height is only about 1".  It spreads to 12".  Leaves are needle-shaped and about .4" long.  Tiny white flowers, produced spring through summer, are about .25" diameter and borne on stems less than 1.5" long.  Its habit is dense, so it chokes out weeds once established.  Pearlwort also tolerates moderate foot traffic.  You can see it makes a perfect lawn substitute, especially for small to medium lawns.  Plant pearlwort between stepping stones, beside walks, in rock gardens and at the fronts of borders.  Eco-conscious gardeners should consider it for their green roofs.  Container gardeners will find it useful as a planting beneath taller perennials and shrubs, maybe even under larger bonsai.

Sagina subulata is hardy in USDA climate zones 4 - 10.  It prefers well-drained soil, but is not particularly drought tolerant.  Soil pH should range from 5.6 to 7.5.  Plant in full sun to partial shade.  Take a soil sample to your nearest Cooperative Extension Service office for proper analysis.  Follow the recommendations.

You wouldn't think a plant that can grow "from a ha'porth of mortar" would need to have the soil prepared before planting, but I recommend it.  Cultivate at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.  Compost may be incorporated into the soil.  Fertilize sparingly.  Incorporate 10-10-10 fertilizer at a rate of no more 1 lb. per 100 square feet into the top 4" to 6" of soil. Avoid synthetic fertilizers contacting any part of your plants.

Space plants 8" to 12" apart.  Dig planting holes into the cultivated soil a little less deep than the depth of the growing container.  Water the plants in the pots, then drain.  Place the plants into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1" deep.

Plant your pearlwort with other species having similar cultural requirements.  It has few insect or disease problems.  Pearlwort is deer resistant.  The greatest cause of failure is over-watering.  Allow soil to dry slightly between watering.

Rosemary - The Herb Of Remembrance


For the sake of some things
That be now no more
I will strew rushes
On my chamber-floor,
I will plant bergamot
At my kitchen-door.

For the sake of dim things
That were once so plain
I will set a barrel
Out to catch the rain,
I will hang an iron pot
On an iron crane.

Those nostalgic lines from Rosemary by Edna St. Vincent Millay may stir similar emotions, if not actual responses in you.  In the language of flowers, rosemary symbolizes remembrance.  Few would strew rushes on the floor in memory of "the good old days", though bergamot may be found by kitchen doors, and rain barrels are becoming more popular.  Iron pots, if you can still find them, are most often used as planters.

Rosemary is also growing in popularity.  Once found mostly in herb gardens, it is now common in ornamental gardens, as well.

Rosemary (Rosmarinus, pronounced rose-mah-REE-nus) is a small genus of perennials including only two species: R. eriocalyx and R. officinalisR. officinalis (pronounced oh-fiss-ih-NAH-liss) is the most popular.

Rosemary is native to the Mediterranean region from Spain to northwest Africa, often near the sea.  Rosmarinus, in fact, means "dew of the sea."  It's a member of the Lamiaceae family which includes mints, lavender, russian sage, and salvia.  Along with many other members of the family, rosemary contains essential oils and was discovered very early on to be beneficial to the body.  Officinalis means "official", referring to its inclusion in the materia medica - that body of knowledge now known as pharmacology.  

Historically, rosemary was used for medicine.  Hippocrates is quoted as instructing, "Let your food be your medicine, and your medicine be your food."  So rosemary was and continues to be used as a flavoring.  Its healthful effects are amazing.   Rosemary is rich in vitamin A, which has a positive effect on vision.  It improves kidney and liver function.  Rosemary is a rich source of iron and stimulates the circulatory system.  Antioxidants in rosemary help to prevent carcinogenic compounds from forming when meat is cooked at high temperatures.  Carnosic acid helps to fight off stroke and neurodegenerative conditions such as Alzheimer's Disease.  It's no wonder that rosemary is known as the herb of remembrance.

If you are tempted to research rosemary to treat yourself, I highly recommend you ask your doctor first.  This is particularly true of women who are pregnant.

Rosemary has evergreen, needle-like leaves that are resinous and fragrant.  Small, light blue flowers are edible and produced throughout the growing season.  The species grows to 48" or more and at least as wide.  Newer cultivars may be more compact.  One cultivar grows prostrate.

Herb gardens, fragrance gardens, hummingbird gardens, bee gardens and butterfly gardens are not complete without rosemary.  It's also very effective in mixed perennial borders for color and textural contrast.  Rosemary responds well to pruning, so it makes a fine hedge.  If your growing space is limited, rosemary performs well in containers.  I've even seen it trained as bonsai.

Where ever you plant it, you'll find yourself stepping out to snip a few sprigs of rosemary for use in the kitchen.  Rosemary can be used in recipes fresh or dry, and is wonderful as an ingredient in aromatic cooking oils.

Rosemary is drought-tolerant, deer and rabbit resistant.  The essential oils may repel some vermin.  Those who live near the sea will appreciate its salt-tolerance.

Hardy in USDA climate zones 7 through 10, rosemary requires full sun and well-drained soils with pH ranging from 6.6 to 8.5.  Take a soil sample to your nearest Cooperative Extension Service office for proper analysis.

Prepare the planting bed by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.  Compost may be incorporated into the soil.  Incorporate 10-10-10 fertilizer at a rate of no more 2 lbs. per 100 square feet into the top 4" to 6" of soil. Avoid synthetic fertilizers contacting any part of your plants.

Space the plants 24" to 36" apart. Dig planting holes into the cultivated soil a little less deep than the depth of the growing container.  Water the plants in the pots, then drain.  Place the plants into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1" deep.

Plant rosemary with other plants having similar cultural requirements.  Fertilize sparingly and allow soil to dry between watering.  The greatest cause of failure is over-watering.  Rosemary is certainly a low-maintenance plant.

Rosemary improves health and pleases the senses.  It enhances the beauty of your garden, cheers the nose and delights the palate.  Do remember to include rosemary in your garden.

Doraji - The Bellflower

Doraji, doraji, doraji! 
I walk over the pass where doraji flowers bloom.
It is a path that is familiar to me.
Doraji, doraji, doraji! 
I look at these white flowers that remind me of my mother,
in the evening with the twinkling stars.
Doraji, doraji, doraji! 
When I wear these white flowers on my hair, 
it reminds me of my young days and my dreams.
---Korean Folk Song, Doraji Bellflower Song.


Plants have a way of taking root in the human consciousness to the point that they become personal, familial, ethnic or national symbols.  Can one mention shamrock, thistle, edelweiss, iris, tulip or rose without a country coming to mind?  Why?  Familiar plants and terrains, familiar beauties and histories, personal and collective memories, shared pathos of grief, love, longing and home.

Doraji (bellflower) possesses particular poignancy for Koreans who are separated from their loved ones and freedom by totalitarianism.  (Photo attributed to www.kremlin.ru.)

Doraji is planted deeply in the hearts of Koreans.  Its native range also includes Japan and China, so Doraji is a part of those cultures, as well.



It is known to us by its English names, Bellflower or Balloon flower, or by its botanical name, Platycodon grandiflorus (pronounced plat-ee-KO-don gran-di-FLOR-us) which means "broad bell, large flowers."  In the language of flowers, bellflower means "thinking of you" with grief implied.

Hungry, needy and wise people have always discovered good uses for the plants around them.  Though they may have never heard of Hippocrates, his wisdom seems to be universal.  "Let food be your medicine."  Chinese emphasized the medicinal properties of doraji roots while Koreans chose to eat them for pleasure -- perhaps to the same end.  Anyway, it's no surprise that Koreans shared a favorite doraji (bellflower) root-gathering song.

Doraji! Doraji! White Doraji!
In the deep, deep forest,
Even after digging only one or two roots,
My basket is overflowing.

Doraji (Platycodon grandiflorus) is a herbaceous (non-woody) perennial that may reach 24" height or more when in bloom with a similar spread.  Newer cultivars may be more compact.  Leaves are dark green, egg-shaped and and pointed.  Blue, pink or white star-shaped flowers, like a pentagram, appear from mid-summer to early fall.

To avoid confusion, you must know that there is another plant that goes by the name Korean bellflower.  Its botanical name is Campanula takesimana.  Though it is a member of the same family, Campanulaceae, Korean bellflower must not be confused with our subject, Platycodon grandiflorus.

In its native habitat, doraji may be found in abundance.  Few gardeners would devote a garden to it, but that would be their mistake.  A mass planting can be spectacular in naturalized meadows.  It's also very effective in mixed perennial borders.  Doraji is also effective in cutting gardens, and herb gardens.  It's perfect for gardens with oriental themes.  The dried, paper-thin blooms are wonderful in dried flower arrangements.

Doraji is deer resistant.

Doraji (bellflower) is generally hardy in USDA climate zones 3 through 9, preferring full sun or partial shade.  Well-drained soil is essential.  Preferred soil pH should range from 6.1 to 7.8.  Take a soil sample to your nearest Cooperative Extension Service Office for proper analysis.  You may pay a small fee.

Prepare the planting bed by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.  Compost may be incorporated into the soil.  Incorporate 10-10-10 fertilizer at a rate of no more 2 lbs. per 100 square feet into the top 4" to 6" of soil. Avoid synthetic fertilizers contacting any part of your plants.

Space the plants 12" to 18" apart for the species, or 10" to 12" apart for compact cultivars. Dig planting holes into the cultivated soil a little less deep than the depth of the growing container.  Water the plants in the pots, then drain.  Place the plants into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1" deep.

Plant doraji with other plants having similar cultural requirements.  Fertilize sparingly and allow soil to dry between watering.  The greatest cause of failure is over-watering.

For cutting and drying, clip doraji with small hand clippers just after flower buds open when dew has dried.  Hang stems upside down to dry in a warm, dry, shady area.  The cuttings should dry within a week.

You might think that a plant as exotic as this would be difficult to grow.  It is not.  Doraji (bellflower) is a plant for beginners.  It may even become your favorite.  I wouldn't be surprised if you began singing your own song about doraji.

Russian Sage - Neither Russian Nor Sage


Russian Sage is not native to Russia.  The genus, Perovskia, is native to the mountains of central Asia, Afghanistan, Kazakhstan, Uzbekistan, Pakistan to China.  Perovskia was discovered in 1840, and probably named in honor of Russian governor and general, Vasily Alekseevich Perovski.

In 1839, when the British were occupied with the First Anglo-Afghan War, Russia seized the opportunity to extend its borders into central Asia.  Led by Perovski, Russian forces invaded The Khanate of Khiva with over 5000 troops and 10,000 camels under the pretense of apprehending slave traders.  Within three months, extreme winter weather forced a retreat at the cost of 1000 casualties without a single battle.

About 12 years later, Perovski returned to The Khanates of Khiva and Kokan with more experience, better planning and weather.  Perhaps the high-point of his military success was the taking of Fortress Ak-Mechet, held by Kokanians "on Russian territory".

Perovski diplomatically informed the Kokands, "Ak-Mechet is already taken, although you are inside it, and you cannot fail to perceive that without losing any of my men, I am in a position to destroy every one of you.  The Russians have come hither not for a day, nor yet for a year, but for ever.  They will not retire.  If you wish to live, ask for mercy; should you prefer to die in Ak-Mechet, you can do so; I am not pressed for time, and do not intend to hurry you.  I here repeat that I do not come to offer you combat, but to thrash you until you open your gates."

His diplomacy being successful, Perovski gained a treaty in 1854 that benefited Russia.  Perovski was made a count.  Fortress Ak-Mechet was renamed Fort Perovski.  By 1924, both Kokan and Khiva (together becoming parts of Kazakhstan) were absorbed into the Soviet Union.  In 1991, the Soviet Union collapsed.  Kazakhstan is now an independent Turkic state.  Some Russians remain.

The cavalry flew by and vanished,
The storm thundered and hushed.
Lawlessness bore down, bore down -
Silence and light all around.

- Mikhail Alekseevich Kuzmin

Flowers also remain, brushed by the wind.

Russian Sage is not a true sage, though it is related as a member of the Lamiaceae family which includes lavender, mint, salvia and such.  Like many of its relatives, its leaves and stems contain aromatic essential oils.  Though known for over a century, it was not used much in ornamental gardens until fairly recently.  The favorite species has been P. atriplicifolia (pronounced at-ry-pliss-ih-FOH-lee-uh).  Being named the Perennial Plant Of The Year in 1995 by the Perennial Plant Association  helped a lot.

From a distance, Russian Sage resembles lavender with its long, wispy stems and small, light blue flowers held above silvery foliage.  Crush a few leaves between your fingers, bring to your nose.  Inhale.  The family connection is obvious.  (This is where I wish technology enabled a "scratch and sniff" link.)

Perovskia atriplicifolia grows to 36" or more and at least as wide.  Newer cultivars may be more compact.

Few gardeners would devote a garden to Russian Sage as they might to roses, but a mass planting is spectacular.  It's also very effective in mixed perennial borders for color and textural contrast.  Russian Sage is also effective in fragrance gardens, cutting gardens, naturalized meadows, butterfly and herb gardens.  It's perfect for dried flower arrangements.  Russian Sage can be grown in short hedges, open fields, borders and knot-gardens.

Do you live in an area with a dry climate?  Is your water use restricted?  When well-established, Russian Sage is drought-tolerant.  Being native to harsh environments, it tolerates inner-city pollution.  Do deer and rabbits come to your garden to dine?  Russian Sage is deer and rabbit resistant.  The essential oils may even repel some insects and vermin.

Flowers of Russian Sage, which appear from late spring to early fall, are edible.  They have a hint of sweetness.  You can sprinkle them on salads, cookies and baked goods.

Historically, Russian Sage has been used medicinally to reduce fever, but I highly recommend you ask your doctor before you try to treat yourself or others.

Russian Sage is generally hardy in USDA climate zones 5 through 9, preferring full sun and well-drained soils with pH ranging from 5.1 to 6.5.  Take a soil sample to your nearest Cooperative Extension Service Office for proper analysis.  You may pay a small fee.

Prepare the planting bed by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.  Compost may be incorporated into the soil.  Incorporate 10-10-10 fertilizer at a rate of no more 2 lbs. per 100 square feet into the top 4" to 6" of soil. Avoid synthetic fertilizers contacting any part of your plants.

Space the plants 24" to 36" apart. Dig planting holes into the cultivated soil a little less deep than the depth of the growing container.  Water the plants in the pots, then drain.  Place the plants into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1" deep.

Plant Russian Sage with other plants having similar cultural requirements.  Fertilize sparingly and allow soil to dry between watering.  The greatest cause of failure is over-watering.

For cutting and drying, clip Russian Sage with small hand clippers just before flower buds open when dew has dried.  Hang stems upside down to dry in a warm, dry, shady area.  The cuttings should dry within a week.

I love plants that are beautiful, fragrant, useful, easy to grow and with stories behind them.  Russian Sage is such a plant.

Wormwood In Legend, Liquid And Garden


Few herbs have been so steeped in legend and liquid as Wormwood.  The botanical name of the genus is Artemisia (pronounced ar-te-MIZ-ee-ah, or ar-tuh-MEEZ-yuh, in the South).  Artemisia is in the Asteraceae or daisy family.  There are over 200 species native to the Northern and Southern Hemispheres.  Most are found in dry climates.  Many of the species are known for their volatile oils useful for medicine and flavoring.

As the name suggests, Artemisia might have been named for the Greek goddess Artemis, also known among Romans as Diana, goddess of the hunt.  Artemis was a vindictive charmer.  Though newly born, she observed the difficult birth of her twin brother, Apollo, and helped her mom, Leto, deliver.  So traumatized by the pain which her mother experienced, Artemis vowed to remain unmarried and childless.  Celibacy, however, was not part of her vow.

Insults, real or imagined, stirred her wrath.  She was especially protective of her mother.  Proud Niobe, daughter of Tantalus, made the mistake of insulting Leto, so Artemis assassinated all her children.  Tityus tried to rape Leto, and paid with his life.  Actaeon, who accidentally saw Artemis naked, was turned into a stag and torn apart by hounds.

Artemis was passionately in love with young Dardamis of Abydos.  He, however, failed to appreciate her beauty and return her affection.  As her final act of cruelty, she poked his eyes out while he slept, then committed suicide.

Artemis, goddess of the moon and of the hunt, was worshiped throughout the Greco-Roman world, principally at Ephesus and Marseilles.  She was also the patron goddess of amazons and unmarried women.  Human sacrifices, presumably male, may have been among the ceremonies.

But there was another Artemis for whom the plant might have been named:  Artemisia II of Carius.  This stunning beauty was wife and sister of King Mausolus.  She was an unusually able queen and admiral of her own fleet.  Botany and plant collecting were among her interests.  Upon the death of her husband, she was stricken with such extraordinary grief that she mixed some of his ashes with her daily draught.  To preserve his memory, she commissioned the building of a majestic monument, a mausoleum, at Halicarnassus to his honor.  Artemis II never saw it completed.  She died in 350 BC, two years after her husband.

Now, Artemisia, the genus, is as legendary.  Two common names, Wormwood and Mugwort, are shared among many of the species, indicating some uses.  Wormwood is derived from Artemisia's use as a repellant of moths, fleas and worms.  Mugwort is derived from its use as a flavoring in beverages, particularly beer and wine.  It was originally an ingredient in vermouth.

A. annua, Sweet Wormwood, is an ingredient in anti-malarial therapy.

A. arborescens, Tree Wormwood, is native to the Middle East.  Very bitter, it is mixed with mint to concoct a drink appropriately known in Israel as Shiva, or "Queen of Sheba."

In addition to its use as a vermifuge, A. absinthium was the key ingredient in absinthe - that notorious green spirit favored by bohemians which was said to eventually caused blindness, abstract paintings and lunarcy.

A. dracunculus, also known as Tarragon, is a mild-flavored wormwood often used as a culinary herb.  In fact, I shall use some tonight on my grilled sea trout.

A. stelleriana (Dusty Miller) and A. schmidtiana are popular ornamental plants.  They are often planted in "moon gardens" because of their silvery sheen and association with Artemis, goddess of the moon.

Artemisia has been used to wean children from their mother's breasts by rubbing the bitter extract on nipples.  Fair Juliet was ablactated just so.

Tis since the earthquake now eleven years,
And she was weaned—I never shall forget it—
Of all the days of the year, upon that day.
For I had then laid wormwood to my dug,
Sitting in the sun under the dovehouse wall.
My lord and you were then at Mantua.—
Nay, I do bear a brain.—But, as I said,
When it did taste the wormwood on the nipple
Of my dug and felt it bitter, pretty fool,
To see it tetchy and fall out with the dug!
Shakespeare - Romeo and Juliet, Act 1, Scene 3

A. vulgaris contains thujone, which is also found in arborvitae (meaning "tree of life").  Arborvitae (Thuja or Platycladus) shrubs are often planted in cemeteries as symbols.  Anyway, thujone is claimed to have many healing properties, and may actually possess them.  But it can be toxic.  Oh well, of such is life.

Speaking of toxic, A. vulgaris is also referred to in the Ukrainian name, Chernobyl, which means "place where the mugwort grows."  Mugwort is known to be an invasive weed that inhabits waste places.  The notorious site was named Chernobyl, perhaps prophetically, before the nuclear (properly pronounced NEW-kew-lahr) meltdown.

The same species has been used to flavor roasted Christmas geese, to smoke, and to tuck into pillows to induce vivid dreams.  Its common names include Felon Herb, Sailor's Tobacco, and Naughty Man - all of which suggest trickery and something to be avoided.

In addition to Shakespeare's Romeo and Juliet, wormwood has figured in other great literary works such as C.S. Lewis's Screwtape Letters, Shakespeare's Hamlet, Rowling's The Draught of Living Death, and in St. John's Revelation.

Artemisia
species are suitable for perennial borders, herb gardens, fragrance gardens, butterfly gardens and container gardens.  Most are semi-evergreen to evergreen, depending upon the climate zone.  Height varies.

Artemisia thrives in well-drained to dry soil.  Take care not to over-water.  There is little need to fertilize.  Hardiness and pH range vary by species.  Since Artemisia is drought tolerant, it's perfect for xeriscaping.

Begin by taking a soil sample to your local Cooperative Extension Service office for testing.  The results will specify any soil amendments needed.

Prepare the planting bed by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.  Add enough soil to raise the bed at least 4" above the surrounding ground level. This will help to promote good drainage. A little compost may be incorporated into the soil.

Plant spacing varies by species. Dig planting holes into the cultivated soil a little less deep than the depth of the growing container.  Water the plants in the pots, then drain.  Place the plants into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1" deep.

Plant Artemisia with other plants having similar cultural requirements.  If you do fertilize, do so sparingly and allow soil to dry between watering.

Artemisia benefits from occasional pruning, but take care not to cut back into old wood.  Prune only during the growing season; do not prune in fall or winter.

Artemisia has no serious pests or diseases, and deer don't like it.  The greatest cause of failure is planting it in an environment that is not to its liking.

Certainly, a plant as interesting as Artemisia should be in your garden.

An Impression of Appleblossom Grass


More than anything, I must have flowers, always, always.
--Claude Monet

Though it's doubtful he knew of it, Appleblossom Grass would have delighted Monet.  Native to Texas and Louisiana, it produces tall stems to 24" bearing white to pink flowers resembling apple blossoms which flutter like butterflies over the landscape from summer to fall.  Their fleeting, impressionistic quality is enchanting.

Appleblossom Grass was formerly known as Guara lindheimeri, but is now included in the genus OenotheraOenothera means "having to do with wine."  It has been suggested that the name comes from the fact that the root of the edible species, Oenothera biennis, was once used to flavor wine.  (I can't imagine why.)  The species is named in honor of Ferdinand Lindheimer, German botanist, revolutionary and political exile, who collected plants for Asa Gray of Harvard University.

For native plant enthusiasts, Appleblossom Grass is a natural.  The species is beautiful enough, but new varieties including 'Siskiyou Pink', 'Whirling Butterflies' and 'Passionate Blush' are growing in popularity.

Appleblossom Grass is perfect for naturalizing in wildflower meadows, being deer resistant and drought tolerant.  It's perfect for xeriscaping.  It also adds charm to perennial gardens.  'Passionate Blush' blossoms last longer than those of other guara, so are better for cut flower arrangements.

Appleblossom Grass thrives in USDA climate zones 6 through 9.  Plant in full sun to partial shade.  Average well-drained garden soil with pH ranging from 6.6 to 8.5 is fine.  Plants can be set any time you have a trowel handy.

Before planting, take a sample of your garden soil to your local Cooperative Extension Service office.  They often provide collection bags.  With each soil sample, indicate the type of plant you intend to grow in it.  For the most basic recommendations, you may be charged a nominal fee.  For more information such as micro-nutrient and organic content you may be charged more.

Prepare the planting bed by cultivating at least 8" deep, removing all traces of weeds.  Adjust soil pH according to soil test results.  Your soil sample report will also include fertilizer recommendations.  Following instructions is always a good bet.  A fine all-around practice is to mix 5 tablespoons of 10-10-10 fertilizer per ten square feet area.  Be careful that fertilizer does not come into direct contact with plant tissue.

Appleblossom Grass looks great planted with cosmos, coreopsis, coneflower, daylily, black-eye susan, yarrow, salvia and mullein.  If you live in a zone where Appleblossom grass can be grown, add it to your garden for a very special impression.

Creeping Charlie Covers Ground


Glechoma (aka Creeping Charlie) does what ground covers do best; it covers ground.  Native to Europe and parts of Asia, Creeping Charlie was introduced to North America by early settlers who carried it with them for its usefulness.  It was described in the 2nd century A.D. for its medicinal properties and prescribed to reduce swelling.  Saxons used it for preserving and flavoring beer.  Even today, tea is brewed from the herb as a satisfying beverage and source of vitamin C.  Once imported to our shores, it took off, and can be found in nearly every region of the country.

(Being an inquisitive fellow, I often wonder why plants were named so.  In this case, who was Charlie?  Why does this plant bear his name?  And who, for that matter was creeping Jenny?  Suspicious characters, perhaps, whose given names remain infamous?)

The genus, Glechoma, is a relative of mints in the Lamiaceae family.  It used to be included in the Nepeta genus, along with Catmint.  You'll see the family resemblance upon inspection.  Glechoma includes about 12 species, with G. hederacea being most common.  Glechoma (pronounced gle-KOH-muh) refers to its minty-fresh relatives.  Hederacea (pronounced hed-er-AY-see-uh) means "having to do with ivy."  Because it grows along the ground, setting down roots where the nodes touch the ground, it is sometimes called Ground Ivy.  Other common names include Gill-Over-The-Ground, Ale-hoof and Tun-hoof, all of which refer to the shape of the leaf and its use by brewers.  The foliage is evergreen, sometimes variegated, with scalloped edges.  Leaf size is about that of a cat's paw, so it is also known as Cat's Foot.  (Any plant having a long association with man is bound to be called lots of things.)  Flowers, produced mid-spring to mid-summer, are light blue.  Height is usually less than 4".

Glechoma grows very low, spreads very quickly, and forms a dense carpet.  Its growth habit might have earned it the name, Creeping Charlie.  But perhaps "creeping" isn't the correct word.  Runaway-Robin, another common name, may be more accurate.

I have often argued that a weed is simply a plant that is in the wrong place, or for which a person is ignorant of a use.  So glechoma is often considered to be a weed, and invasive at that.  As a medicinal herb may be anti-inflammatory, but for its detractors it's provocative.  For them I suggest that they exhibit some tolerance.  Either don't plant it, plant it in the right place, or brew it.  Live with it.

Glechoma, as you know by now, is an excellent ground cover.  (Who would want a ground cover that doesn't cover ground?)  It performs better in shade than most grasses.  It is more drought-tolerant than many grasses.  It tolerates foot traffic very well.  It doesn't require mowing.  It smells good when you tread on it.  So forget about the grass and grow glechoma.  More good news:  it's deer resistant!

It also looks great in hanging baskets, container gardens, and cascading over the edges of planters and terraces.  For collectors of herbs with historical or medicinal interest, it's a natural.

Glechoma thrives in full sun to full shade in well-drained soils with pH ranging from 6.1 to 7.8.  It is hardy in USDA climate zones 4 through 9.  That just about covers everything.

Before you plant, take a soil sample to your local Cooperative Extension Service office for testing.  The fee is nominal, but that's because you're already paying for their services with your tax dollars.  (Use it or lose it.)  The results will specify any necessary soil amendments.

Prepare the planting bed by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.  Compost may be incorporated into the soil.  Incorporate 10-10-10 fertilizer at a rate of no more 2 lbs. per 100 square feet into the top 4" to 6" of soil. Avoid synthetic fertilizers contacting any part of your plants.

Space the plants 24" to 30" apart. (How economical is that?  Extremely so.) Dig planting holes into the cultivated soil a little less deep than the depth of the growing container.  Water the plants in the pots, then drain.  Place the plants into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1" deep.

Plant glechoma with other plants having similar cultural requirements.  Fertilize sparingly and allow soil to dry between watering.

This is a low-maintenance plant, having no serious pests or diseases.  The greatest cause of failure is planting it in an environment that is not to its liking, but most are very much to its liking.

With all this in mind, you should know that glechoma will not take over your earth.  You are the boss.  Establish its limits.  Glechoma should work very well for you.

Asiatic Jasmine - Cover Ground With Southern Style


Asiatic Jasmine ( Trachelospermum asiaticum ), is a marvelous ground cover vine that is well-known throughout the South. Trachelospermum asiaticum means "rough seed from Asia", but it doesn't imply that the plant is without style. Evergreen, leathery leaves with a glossy sheen form a dense, luxurious blanket that adds a touch of class to the landscape.

The species is distantly related to plants such as Vinca, Mandevilla, Carissa, Oleander and Amsonia. Confederate Jasmine (Trachelospermum jasminoides) is a closer relative, and very similar in appearance, but Asiatic Jasmine differs from T. jasminoides by having smaller leaves, being shy to bloom and reluctant to climb.

Asiatic Jasmine is native to Korea and Japan, but is so popular in the southeastern U.S. that you might think it's from around here. In fact, there is a species, commonly called Climbing Dogbane (Trachelospermum difforme), which is native to the U.S.

It must be noted that Asiatic and Confederate jasmines are not among what some consider to be "true jasmine" of the genus Jasminum.

Foliage is about 1" to 2" long. Insignificant star-shaped flowers are about 1" diameter, white to pale yellow. Variegated-leaf forms exist. Mature height as a ground cover is only 6", but vines may extend to 24" when prostrate. If Asiatic Jasmine does take the notion to climb, the vines my grow to 72" or more.

Asiatic Jasmine is cold-hardy in USDA climate zones 7 through 9. It is perfect for full, but will grow in partial- to full shade. Deep shade is not recommended. Plant in average, well-drained soil with pH ranging from 6.1 to 7.8. Plants are drought tolerant when established, and heat-loving.

It's very effective as a ground cover in small to large areas. If grown near a walkway, occasional edging will keep it very neat. Otherwise, maintenance needs are few. Deer won't eat it, and you shouldn't either. The milky sap will irritate sensitive tissue, so keep it out of your eyes and nose.

Prepare the planting bed for Trachelospermum asiaticum by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 12" deep. Compost may be incorporated into the soil. Fertilizer may be used. If you choose to do so, incorporate 5-10-15 fertilizer at a rate of no more 2 lbs. per 100 square feet into the top 4" to 6" of soil. Avoid synthetic fertilizers contacting any part of your plants.

Plant container-grown jasmine at 18" to 24" spacing. Dig planting holes into the cultivated soil a little less deep than the depth of the growing container. Place the plants into the holes and back-fill, watering as you go. Press soil around the roots. Do not cover the root balls with soil. The tops should be slightly exposed.

Smaller, bare root plants may be spaced 8" to 15" apart. Plant only as deeply as they were previously grown. A slight change in stem color and texture should be visible, indicating the planting depth. Add a top-dressing of mulch around the plants, not on top of them, about 2" deep.

Asiatic Jasmine is one of my favorite ground cover vines. Rich foliage color, glossy sheen and low-maintenance needs make it very popular with many other southern gardeners, as well.

Veronica - Holy Remembrances and Healing Attributes


D

A woman of Jerusalem pitied Jesus as he carried his cross to crucifixion, stepped forward and wiped his face with a cloth.  Blood and sweat stained his likeness upon the napkin.  Thus, according to legend, was Christ's true image (vera eikon) preserved.  Other stories identify the woman as Berenike, possibly the woman Jesus healed of a bloody hemorrhage.  It is claimed that Berenike, for some inexplicable reason, carried the cloth to the bedside of the ailing Roman Emperor Tiberius, and cured him with it.  (Tiberius, very unpopular, was later assassinated by smothering.)

Veronica - Hans Memling

Somehow the name, Veronica, evolved from vera eikon or "Berenike" and was bestowed upon the celebrated lady.  Much later, the name was given to an herb.  I have no idea why.  Maybe the plant was discovered on Shrove Tuesday or on July 12, when St. Veronica is remembered.  Perhaps the name was given in honor of the botanist's daughter or wife.

Quite possibly the name was bestowed upon the plant because a very common species native to Europe and western Asia, Veronica officinalis, has been used medicinally to alleviate coughing.  An Experimental History Of The Materia Medica, by William Lewis (c. 1791) records that the herb was used to treat "disorders of the breast both catarrhous and ulcerous, and for purifying the blood and humours."  The use may have preceded the name and inspired the appellation.  I expect we shall never know.

Veronica is a genus of about 500 species native to the Old World as well as the New in both hemispheres.

Depending on the species, Veronica may be hardy from USDA climate zones 3 through 9.  Plant in well-drained soil with exposure to full sun.  Recommended pH ranges from 6.5 to 7.8.

Height varies, but most grow less than 12" tall.  They are excellent for ground cover, perennial borders, rock gardens, container gardens and terraces.  Some are drought-tolerant.  Veronica attracts butterflies, too.  Deer and rabbits tend to leave most species alone.

Prepare the planting bed for Veronica by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 8" deep. Compost may be incorporated into the soil. Synthetic fertilizers may be used. To best determine your soil's needs, take a soil sample to your nearby Cooperative Extension Service office for testing for a small fee.

Container-grown Veronica can be planted any time you have a trowel handy, but will require monitoring of soil moisture levels during hot weather to avoid plant stress.  Take care not to water too much.  Let soil dry between watering.

Space plants 12" to 24" apart. Keep in mind that my spacing recommendations are approximate. Dig planting holes into the cultivated soil a little less deep than the depth of the growing container. Place the plants into the holes and back-fill.  Press soil around the roots. Do not cover the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 2" to 4" deep. Irrigate thoroughly.

Maintenance is minimal. Veronica plants have few pest and disease problems, but they aren't immune. The best preventative is to maintain vigorous plants in a healthy environment.  Over-watering can be the death of them.

Whether you collect plants for beauty, their history, attractiveness to butterflies or herbal properties, Veronica should be included in your garden.  With so many species to consider, it's likely that you can find one just right for you.
