Eucomis - Tropical Pineapple Lily


Of all the tropical bulbs I know, Pineapple Lily is one of the most amusing, resembling a tousle-headed cartoon character from outer space.  Long spikes up to 24" appear in late summer to early fall, bristling with hyacinth-like flowers and topped with a crown of leafy green.  Flower colors range from light green to purple.  The common name is inspired by the plant's resemblance to the tropical fruit.

Pineapple Lily belongs to the genus Eucomis (pronounced YOU-com-iss), which name is a combination of two Greek words meaning "beautiful hair of the head".  It is a member of the Hyacinthaceae family.  Eucomis comprises about a dozen species native to South Africa, Botswana, Lesotho, Swaziland, Malawi and Zimbabwe.  Their native habitat includes grassy savannas, forests, near rivers and swamps.  They are rarely found in arid regions.

Eucomis was introduced in 1878 by the famous James Veitch and Sons nursery near Exeter.  The Veitch nursery was one of the most important nurseries in the UK.  The family is immortalized in the names of many ornamental landscape plants.

Eucomis adds a bold, tropical appearance to the landscape.  It is very suitable for perennial borders and container gardens.  An African or tropical theme garden would be incomplete without lots of them. 

Pineapple lily is cold hardy in USDA climate zones 7b to 11. Gardeners in colder climates lift and store them over winter for planting the following spring.  Take a sample of your garden soil to your local Cooperative Extension Service office before planting.  For a nominal fee, they will send it to a lab for analysis and recommendations.

Eucomis prefers full sun and average, well-drained garden soil.  Prepare the planting bed by cultivating at least 8" deep, removing all traces of weeds.  A good all-around practice for bulbs and such is to mix 5 tablespoons of 10-10-10 fertilizer and 2 cups of bone meal per ten square feet area of bulb garden.  Repeat the application when growth appears, but be careful that fertilizer does not come into direct contact with plant tissue.

Plant the Eucomis bulbs about 4" deep.  Depth is measured to the bottom of the hole.  Space the bulbs 8" to 12" apart.

Eucomis requires very little maintenance.  It is perennial, so you can leave the plants undisturbed for years.  Water regularly, but don't over-water.  If planted in a windy area, the flower stalks may require staking.  After blooming, be sure to let the leaves yellow and die before cutting them.  Leaving them alone will allow the bulbs to build up food reserves for a glorious show the next year.

Though introduced over 130 years ago, Eucomis may be a new discovery to many gardeners, and perhaps to you.  If you've not tried this novel Pineapple Lily, you should include it in your garden this coming spring.

Discover Hardy Gloxinia


Alexander von Humboldt (1769 - 1859), German traveler and explorer once complained, "People often say that I'm curious about too many things at once: botany, astronomy, comparative anatomy.  But can you really forbid a man from harbouring a desire to know and embrace everything that surrounds him?"

Humboldt had been trained in biology, geology, chemistry, physics and history.  With knowledge and wanderlust, he followed his passion and traveled to South America to explore the continent.  Following his five-year journey, he published over the next twenty years a thirty volume account of his exploration, and introduced the world to wonders of that continent.  Charles Darwin considered him "the greatest scientific traveler who ever lived."

Pierre Nicolas Le Chéron d'Incarville, following his passion, also introduced the world to exotic wonders.  Those, however, were of the Orient.  d'Incarville's first passion was to take Christianity to China.  As a Jesuit missionary, he was charged to convert the Qianlong Emperor.  The emperor was not interested, but they developed mutual respect based upon their common interest in plants.  While in China, d'Incarville wrote several works on China which were published in Europe, including a French-Chinese dictionary.  He also catalogued Chinese plants and sent back seeds unknown to Europe.

A genus of plants which he introduced to the West was given his name to honor his work:  Incarvillea (pronounced in-car-VIL-ee-uh).  The genus contains about 16 species, all native to central and eastern Asia.

Jean Marie Delavay (1834–1895) was another who was curious about many things at once.  A French missionary to China, he was also passionate about plants and exploration.  His missionary zeal worked both ways, for as he worked to introduce Chinese to Christ, he worked to introduce France to the plants of China.  He sent over 200,000 specimens to his homeland.  From them, over 1500 new species were discovered.

Several plants commemorate Father Delavay's work in their names.  One is Incarvillea delavayi (pronounced del-uh-VAY-ee), a species that honors two great plant explorers at once. 

I. delavayi, also known as hardy gloxinia, is a lovely selection for the garden.  With velvety, deciduous foliage, it grows to 24" tall and produces showy pink or white flowers.  The flowers appear in late spring to mid-summer.  They're fragrant, too, and great for cutting.  Plants self-sow readily from seed.  Many gardeners include hardy gloxinias in their butterfly gardens.  They are also suitable for container gardens, and can be grown indoors.

I. delavayi is cold hardy in USDA climate zones 6 to 10.  The site should be in full sun or partial shade.  Soil should be well-drained, with pH ranging from 6.1 to 7.8.  Incarvillea is drought-tolerant, so is often chosen for xeriscaping.  That said, however, Incarvillea flowers best when the soil is slightly moist.

As always, take a sample of your garden soil to your local Cooperative Extension Service office before planting.  They will send it to a lab for analysis and recommendations.  Expect to pay a nominal fee.  If you don't understand the report, ask the County Agent to interpret it for you.

Planting begins in spring.  Prepare the planting bed by cultivating at least 8" deep, removing all traces of weeds.  A good all-around practice is to mix 5 tablespoons of 10-10-10 fertilizer and 2 cups of bone meal per ten square feet area of garden.  Repeat the application when growth appears, but be careful that fertilizer does not come into direct contact with plant tissue.

Plant hardy gloxinia tubers about 3" to 5" deep.  Depth is measured to the bottom of the hole or trench.  If the tubers are separated, they may be planted horizontally.  Recommended plant spacing is 12" to 15" apart.  Water well, then let the soil become slightly dry before watering again.  The plants don't require much maintenance.

Unfortunately, hardy gloxinias are not planted widely enough.  When discovered, gardeners often try them out of curiosity.  But it is that desire to know and embrace that characterizes plant lovers.  So follow that desire to explore.  Try hardy gloxinias in your garden.

Enjoy The Fragrance Of Summer Hyacinth


When warm breezes bear their fragrances, Summer Hyacinth should be among them.  Also known as Galtonia candicans, Summer Hyacinth brings the beauty of hyacinths to your late summer garden.  It's a member of the Hyacinthaceae family, perennial plants that grow from flower bulbs.  The blooms are much taller than Dutch Hyacinths.  Flowers are produced in late summer to early fall on stems up 48" to long.  After flowering, the leaves yellow and die.

The genus, Galtonia (pronounced gal-TOH-nee-ah), was named to honor the brilliant Sir Francis Galton (1855 - 1911).  Galton was a man of exceptional genius and a member of a family of Victorian notables, including Charles Darwin.  Not simply a dabbler, he was an accomplished explorer, anthropologist, inventor, meteorologist, geographer and statistician.  Galton also founded such disciplines as eugenics and psychometrics, and laid the foundation in the study of genetics.

G. candicans (pronounced KAN-dee-kans) is arguably the most popular of the few Galtonia species.  Candicans refers to the white color of the bell-shaped flowers.  It is native to South Africa.

Summer Hyacinth is cold hardy in USDA climate zones 6 to 8 if mulched during winter.  It is completely cold hardy in climate zones 9 to 10.  Gardeners in colder climates can grow Summer Hyacinth plants in containers or in the garden, dig them in fall, and store them over winter.  However, it must be noted that Summer Hyacinths really don't like to be disturbed.

Summer Hyacinths thrive in full sun and well-drained soil.  Best pH should range from 6.5 to 7.5.

As always, take a sample of your garden soil to your local Cooperative Extension Service office before planting.  They will send it to a lab for analysis and recommendations.  Expect to pay a nominal fee.  If you don't understand the report, ask the County Agent to interpret it for you.

Planting begins in spring.  Prepare the planting bed by cultivating at least 8" deep, removing all traces of weeds.  A good all-around practice for bulbs and such is to mix 5 tablespoons of 10-10-10 fertilizer and 2 cups of bone meal per ten square feet area of bulb garden.  Repeat the application when growth appears, but be careful that fertilizer does not come into direct contact with plant tissue.

Plant the bulbs about 6" deep.  Depth is measured to the bottom of the hole.  Recommended plant spacing is 8" to 12" apart.

The plants require very little maintenance.  Plant them and forget about them.  They are wonderful for bulb gardens, perennial gardens, container gardens.  Summer Hyacinths are superb as cut flowers.  They last a long time.  The white blooms are wonderful when contrasted with plants having darker colored foliage and flowers.  After blooming, be sure to let the leaves yellow and die before cutting them.  Leaving them alone will allow the bulbs to build up food reserves for a glorious show the next year.  Believe me, a generous planting of Summer Hyacinths will delight the eye and nose.

Enchanting Hardy Cyclamen


I pluck the cyclamen
red by wine-red
and place the petals
stiff ivory and bright fire
against my flesh

Now I am powerless 
to draw back
for the sea is cyclamen-purple
cyclamen red, colour of the last grapes
colour of the purple of the flowers
cyclamen-coloured and dark.

 - H.D., from The God

Cyclamen (pronounced SIGH-kla-men) is a genus of 23 species of perennials mostly native to the Mediterranean region, and often naturalized elsewhere.  The name refers to the twisted flower stalks of some species.  Flower colors range from white to deep burgundy.  With their alluring, swept-back petals and charming foliage, cyclamen are captivating.  Perhaps that is why some are so popular as gift plants.

Daniel Foley, Editor of Horticulture and staff member of the Massachusetts Horticultural Society, wrote that Cyclamen europaeum "which was dedicated to Mary was also used as a charm against bad weather. From the angle of its blooms on their stems it was known in Germany as Our Lady's Little Ladles."  Others, Paghat for example, suggest that the genus has associations with witchcraft (that's possible) and that the oil of cyclamen applied externally has mysterious powers beneficial to women (that's doubtful).

In literature, cyclamen were considered to be so enchanting that children seeking them in the forests might never return.

The gentle cyclamen with dewy eye
Breathes o'er her lifeless babe
The parting sigh;
And bending low with pious hands
Inhumes her dear departed in the sands.
Sweet Nursling, withering in thy tender hour,
"Oh, sleep," She cries and rise a fairer flower!"

- Erasmus Darwin, The Botanic Garden

It's more complicated, but you can see the symbol of the BVM in Darwin's poem.  Keep in mind that, like very many ornamental plants, cyclamen are toxic if eaten.

Unfortunately, the most popular gift species, C. persicum, is not cold-hardy, so it comes as a surprise to many of today's gardeners that some cyclamen species may actually be grown outdoors.  But gardeners in ages past knew it for hardy cyclamen, flowering in autumn and winter, were often grown in cemeteries to provide seasonal color.

Cyclamen hederifolium, also known as C. neapolitanum, (seen in the photo above) may take cold weather best.  Hederifolium (pronounced hed-er-ih-FOH-lee-um) means "having leaves like Hedera (the ivy genus).  Common names include Hardy Cyclamen and Ivy-Leaved Cyclamen.  It is certainly the most widely cultivated among the hardy cyclamen.  It is a lovely little plant, native from southern France to western Turkey, that adds charm to the shady corner of your garden.  You'll enjoy the ivy-shaped, variegated foliage and fragrant, pink flowers from late summer to early fall.  Though very similar in appearance to the florist cyclamen, hardy cyclamen thrives outdoors in USDA zones 5 through 9, performing best in light shade.  It even produces seed and self-sows readily when conditions are to its liking.  Soil should be well-drained but slightly moist.  Take care not to over-water.  Recommended pH is 6.1 to 7.8.  Take a soil sample to your nearby Cooperative Extension Service office to determine the soil pH.

They can be grown from seeds, stem tubers or established plants.  Planting stem tubers combines reliability and economy.

Cyclamen tubers will be firm.  Roots grow from the sides and bottom.  The tops will be slightly rough with some little bumps from which new growths emerge.  Plant cyclamen tubers in the spring.  When planting, space the tubers about 10" to 12" apart and cover with 1" to 2" of soil.  Water well and gently, taking care not to wash the tubers out of the soil.  Allow the soil to become dry before watering again.

Hardy cyclamen are sure to delight you.  Whether they will ward off bad weather or bestow mysterious benefits is doubtful.  But I believe that if you plant some in your garden and become beguiled by their beauty, you will still return safely indoors.

FAQ: Why do my grapes fall off the vines?

Q. I have Muscadine vines that have, after many years, covered my arbor.  It's about 12' x 18' x 8' high.  The soil is very poor,  yellow sandy soil.  I have 6 or 7 plants planted around the perimeter which now cover the top.  I give each each plant 4 or 5 cups of 10-10-10 fertilizer in February and I give them a lesser amount in June.  I have never pruned these vines, but I intend to this February.  I generally do not water them, except in very dry weather.  This arbor does not get full sun, probably one side gets morning sun and the other side gets afternoon sun.  My problem is, I get a good stand of fruit, but the fruit falls off when the grapes are very small.  I got like two very small grapes that actually ripened.  Also, I noticed some of the leaves were being eaten by something very small.  I never could see the culprit.  Not all over the arbor, just here and there.  Would you have any idea why my grapes fall off the vines and what should I do about these "bugs" eating the grape leaves?

A. I'm not sure exactly why the grapes are falling off, but if they fall off after your June fertilizer application, that could be the reason.  Ideally, your vines should receive full sun to produce higher yields, but they don't, so there's no sense in discussing that.  Muscadines are native to wooded areas anyway.  They don't naturally grow in open fields.  Excess nitrogen can cause fruit drop.  I believe this is the problem.  You probably don't need to fertilize them in June.  There may be another problem, perhaps a micro-nutrient deficiency.  Extremely dry soil conditions can also cause fruit drop, but I suspect that it's related to fertilizer application.

It sounds like the bugs (or whatever) that are eating some grape leaves are not causing a significant problem.  Some sort of beetle may be the culprit, but I wouldn't worry about it unless the problem becomes severe.

Your vines should be pruned annually, so it's good that you have that planned for this winter.

FAQ: Do you think recycled rubber mulch is a good choice?

Photo by Magda Ehlers from Pexels

Q. Do you think recycled rubber mulch is a good choice?

A. No, I don't. Rubber mulch is usually made from old tires. While it may seem that recycling rubber in this way is a good idea, I don't agree. Rubber doesn't decompose like organic materials. Decomposed organic materials help to build soil health. Recycled rubber is easy to ignite and difficult to extinguish if set aflame by some means. Furthermore, I don't like the appearance of recycled rubber.

The Cummer Gardens of Jacksonville, Florida


Jacksonville, Florida holds many fond memories for me.  Quite a few relatives lived there when I was a child.  Whether by automobile or different trains, the trip to Jacksonville was an adventure.  Sometimes my father, a Chiropractor and Naturopath, would include a visit to Dr. Emil Weise, another Naturopathic physician and friend.  A highlight of one trip was a visit to Aunt Anne Palmer's garden.  Meandering grassy paths wound among beds of camellias, azaleas and ginger lilies toward her greenhouse where she nurtured her orchids.  I was enchanted.  Uncle Jim, her husband, owned Packard Florida Motors Company on Riverside and Rosselle.

We returned recently to visit the Cummer Museum of Art and Gardens, just a few blocks from where Uncle Jim's business once stood.  The neighborhood has changed quite a bit since the 1950s and '60s.  Many of the old homes have been replaced, including the tudor-style home of Arthur and Ninah Cummer.  The Cummer Museum now stands on the site.  The garden is as grand and well-loved as before.

Arthur Cummer (1894-1943) was the son of a wealthy lumber magnate from Cadillac, Michigan, who found Jacksonville to be very much to his liking.  The climate and forests of Florida attracted the family.  Arthur was also a partner in the Cook-Cummer Steamship line which transported Cummer Lumber Company products to markets along the Gulf Coast and Eastern Seaboard.  Readers interested in stories involving Cummer steamships should find the New York Times accounts of the Great Jacksonville Fire of 1901 and of the sinking of the John J. Hill to be stirring.

Strong believers in civic responsibility, Arthur and Ninah Cummer (1875-1958) were actively involved in organizations to benefit the public.  As Board President, Arthur helped enlarge the historic Evergreen Cemetery of Jacksonville.  Ninah, an art collector, passionate gardener and garden club member, created an endowment in 1958 to build an art museum and to preserve her beloved gardens.

Though the appearance of much of Jacksonville's Riverside Avenue has changed, the vista from Cummer Gardens across the St. John's River is very much like the atmosphere I remember from my visit to Aunt Anne's oasis.  The Cummer Gardens, however, are far grander.

The Gardens consist of three:
Upon entering the Gardens from the museum's Uible Loggia, the first thing to capture the eye is an elegant sculpture, Diana of the Hunt, a gift of sculptor Anna Hyatt Huntington.  (I visited Atalya, Huntington's moorish-style home/studio in South Carolina a few years after her death.  Though near the shore, it struck me as a rather bleak, fortress-like residence.)  According to myth, Diana (aka Artemis) was not as elegant as artists imagine but exquisitely bad-natured.  From the upper terrace, the enticing vista across the English Garden opens toward the beautiful St. John's River.

Moseying to the right, the Tea Garden invites the visitor to sit a moment in one of the historic barrel chairs that originally belonged to Wellington and Ada Cummer, Arthur's parents.  Concrete and mosaic pedestal planters designed by William Mercer add visual impact to the adjacent parterres.

Further along, the Peacock Fountain, also designed by Mercer, adorns the South Wall in a shady nook.  Before the Peacock Fountain, another called Two Children with a Goose fills a pool also designed by Mercer.  The original Two Children with a Goose can be seen in London's Victoria and Albert Museum.  This section is part of the English Garden, designed in 1903 by Ossian Cole Simonds (1855-1931).  Simonds was a founder of the American Society of Landscape Architects.  Cummer's English Garden was redesigned in 1910 by Thomas Meehan and Sons of Philadelphia, PA.  At river's side, a fine wisteria arbor provides a shady retreat refreshed by gentle river breezes.

One can't help but linger at the railing to enjoy the view across the St. John's river.  Mr. Cummer relished an earlier scene from his own putting green between the English and Italian gardens.  The private green, a rare pleasure in those days, was given to him by his wife, Ninah.

The Italian Garden was designed in 1931 by Ellen Biddle Shipman (1869-1950), perhaps the most significant among female American landscape architects.  Ninah Cummer commissioned the work after visiting the Villa Gamberaia near Florence, Italy   It features a gloriette, the archways of which frame a lovely fountain that replicates one Mrs. Cummer purchased in Italy in 1930.  At the end of the river walk, you will find a tile-roofed garden folly which serves no other purpose than to adorn the garden, or perhaps to offer another shady retreat for a tête-a-tête.

The North Wall of the Italian Garden is adorned with another feature designed by William Mercer.  A medallion of flamingos overlooks a lion's head planter with Della Robbia swags.

As one would expect, a pair of reflecting pools mirror all that surrounds them above and below.  The sky, roses, italian cypresses (Cupressus sempervirens)  and azaleas all shimmer in the water's surface.

Leonine motifs recur throughout the Italian Garden.  The Lion Sculpture is one of the many pieces that the Cummers purchased during their visit to Itay in 1930.  Garden benches repeat the theme.

When the Cummers began to establish their gardens, some plants now so common to the South were not well-known in Florida.  Agapanthus and azalea collections were rare.  The Cummers sought them out.  Both grow luxuriantly in the Cummer Gardens.

Upon returning to the Upper Terrace, one passes beneath the magnificent Cummer Oak.  The canopy of the verdant giant spans over 150 feet.  Aged over 175 years, it is one of the oldest and most revered trees in the city.  To rest beneath its ancient limbs and reflect upon the beauty of the garden is another of the visitor's rewards.

Thanks to the generosity of the Cummers, along with the dedication of museum staff and volunteers, the Cummer Museum of Art and Gardens presents one of the premier gardens in the United States.  Though comprised of only two acres, it is a historically significant site that you should include in your garden visits.

How To Care For Cedar Wood Furniture


Northern White and Western Red Cedar are very desirable woods, perfect for indoor and outdoor use.  Northern White Cedar is very popular with homeowners who prefer a rustic decor for vacation homes and cabins.  Western Red Cedar is preferred by those who desire a more refined appearance.  Both are durable, resistant to insects and rot.  They can be left natural and untreated, or can be painted or stained.

If left untreated, cedar wood will turn to a silvery gray color. Untreated cedar is quite beautiful, however, the wood may become discolored by algae over time if exposed to excessive dampness in shaded areas.  A solution of 1 part non-chlorine bleach to 5 parts water with 1 ounce of detergent per gallon of solution will usually eliminate such stains.  Even after years of use, cedar can be refinished by sanding to a bright clean appearance.

If you decide to stain your cedar furniture, there are many types of stains.  Penofin is highly recommended because it enhances and maintains cedar's natural beauty. Some stains also have water and mildew repellent ingredients.  Penetrating stains soak into the wood without leaving a barrier on the surface.  So the the surface of the wood doesn't blister or peel like painted surfaces.  Natural cedar wood usually has knots, deep surface texture and other unique characteristics which are beautifully enhanced by penetrating stains.  For best results, always follow stain manufacturers' instructions.

If you opt to paint your cedar furniture, be aware that the natural color and grain of the wood will be hidden.  However, there are so many wonderful shades of paint on the market, you can let your imagination run wild.  Match your existing décor, or change the look as you wish.  Bright solid colors, floral patterns and designs from nature can be painted on the furniture.  As always, follow the manufacturers' instructions on the label for best application results.

FAQ: What Is Recycled Poly Lumber?


Recycled poly (plastic) lumber, also known as RPL, is a product made from recovered plastic which looks like lumber and can be used as a wood substitute.  There are many applications for which RPL can be used.  RPL is increasingly used for fencing, railings, decking, flooring, retaining walls, shipping pallets, park benches and picnic tables, playground equipment, sign posts, and even for dock pilings and seawalls.  We at GoGardenNow.com include bird houses and bird feeders constructed of recycled poly lumber among our product offerings in our eBay store. 

There are several different types of recycled plastic lumber available.  The type used in our products is a high-density polyethylene, the same material found in plastic milk jugs.  Other types may include additional materials in the mix such as thermoplastic, sawdust, fiberglass, rubber, concrete, or even steel reinforcing rods.

Recycled plastic lumber has distinct advantages over wood.  It is nontoxic, nonporous, and lasts longer than wood, unless it is one of the types that contains sawdust.  RPL is moisture resistant and does not rot, therefore it does not require maintenance with sealants or preservatives.  It is chemical resistant.  It does not crack or splinter like wood.  Painting is unnecessary because the plastic is colored throughout, and the colors never fade.  Insects will not eat it, and it does not absorb bacteria or other pathogens.  As you can see, RPL is maintenance free.  Furthermore, RPL is flexible, and can be shaped with common wood-working tools.
By recycling plastics into poly lumber, wood and plastic waste in landfills is reduced.

You can feel good about purchasing bird houses and feeders constructed of recycled poly lumber, knowing that you are buying eco-friendly products that require little or no maintenance.

How To Choose and Maintain A Birdbath

A birdbath is an essential element for bird habitat.  This article gives a few tips on how to choose and maintain a birdbath.

The birdbath in our back yard is a wonderful source of entertainment for our family.  We can see it clearly from our family room window.  The birdbath provides refreshment, discourages mites, and provides drinking water.  It's great fun to watch birds refreshing themselves in watery sprays, and it's amazing how many species are attracted to it.  Some of the species we've recently seen bathing include painted buntings and a pair of barred owls.

Whether purchasing a large or small birdbath, choose one that gently slopes toward the center.  This provides various depths for small and larger birds alike.  The water should be no deeper than 2" in the center.  The birds only want to bathe, not swim laps.

While providing a birdbath is a welcome favor, maintaining a clean one is also very important.  You wouldn't want to take a nasty bath, would you?  Cleaning your birdbath is necessary to prevent the spread of avian diseases such as Aspergillosis, Avian Pox, Salmonellosis and Trichomoniasis.  Birds who are already suffering from diseases are drawn to birdbaths just as healthy ones are.  Pathogens left behind can then infect others.

Change the water in your birdbath every day.  Wipe or brush it clean.  This will help to prevent algae buildup, as well as to remove other debris.  We have a large concrete birdbath with sloping sides, so we use a wire brush.  Rinse your birdbath, then refill it with clean water.

Disinfect your birdbath to eliminate germs and mites.  We use a solution of one part non-chlorine bleach to nine parts water, scrubbing and rinsing thoroughly one or twice per month.

Birds are especially attracted to moving water.  A dripper or spray will provide the right amount of activity.  In addition, moving water tends to discourage mosquitoes.

Birds appreciate bathing even in winter.  If you live in a region where standing water may freeze overnight, invest in a small, submersible electric heater or a heated birdbath.  When cold weather approaches, be sure to check the wiring for damage that may have occurred during storage.  Replace the appliance if damage is apparent.

Be sure to place the birdbath somewhere you can enjoy watching it.  The birds also appreciate the presence of trees or shrubs nearby so they can return to the birdbath again and again.

Six Steps to Turn Your Yard into a Sanctuary for Birds

The following article published by the Wild Bird Feeding Industry (reproduced by permission) is full of helpful tips.

Birds need your help! Populations of many kinds of birds are declining. Habitat loss and degradation, disease, collisions with man-made structures and a host of other factors contribute to these declines. You can help by turning your yard into a sanctuary for birds.

Here are six steps you can take to make the future brighter for birds:

1. Put out the welcome mat! Habitat loss is the biggest challenge facing birds. You can help by making your neighborhood more attractive to birds by landscaping with native plants that provide natural food sources, shelter from the elements and predators, and nesting sites. Providing feeders, nest boxes and water also benefits birds. To learn how, stop by your local wild bird shop or garden retailer.

2. Prepare a proper menu. Providing the appropriate foods year round will attract more birds to your yard and help ensure that they have a safe and nutritious diet. Refill feeders regularly with food desired by birds in your area. To pick the best menu, stop by your local wild bird shop.

3. Keep feed and feeding areas clean. To help reduce the possibility of disease transmission in birds, clean feeders and feeding areas at least once a month. Plastic and metal feeders can go in the dishwasher, or rinse these and other styles with a 10% solution of bleach and warm water. Scrub birdbaths with a brush and replace water every three to five days to discourage mosquito reproduction. Rake up and dispose of seed hulls under feeders. Moving feeders periodically helps prevent the buildup of waste on the ground. Keep seed and foods dry; discard food that smells musty, is wet or looks moldy. Hummingbird feeders should be cleaned every three to five days, or every other day in warm weather. It’s good hygiene to wash your hands after filling or cleaning feeders.

4. Birds and chemicals don’t mix. Many pesticides, herbicides and fungicides are toxic to birds; avoid using these near areas where birds feed, bathe or rest. Always follow directions provided by chemical manufacturers. For additional information visit your garden retailer.

5. Keep cats away from birds. Scientists estimate that cats probably kill hundreds of millions of birds each year in the U.S. This is a big problem, but it’s easy to fix. Many people who enjoy feeding birds also love cats. The best solution is to keep cats indoors. They will lead longer, healthier lives, and your yard will be safer for birds. Install feeders in areas not readily accessible to cats or install fences or other barriers to help keep stray cats from feeder areas. Collar bells, de-clawing and keeping cats well fed will not solve the problem.

6. Reduce window collisions. Collisions with glass windows kill millions of wild birds every year. Depending on their size and location, some windows reflect the sky or vegetation, and birds are fooled into thinking they can fly through them. To eliminate this problem identify windows that cause collisions (typically larger, reflective windows, those near the ground, or those that “look through” the house). Attaching decorative decals or other decorations to the outside surface of the glass can reduce reflections. Feeder birds fleeing predators are vulnerable to window collisions. If this is happening at your house, consider moving feeders within three feet of the windows so that birds cannot accelerate to injury level speeds while flying away. Problem windows can be covered with a screen so that birds bounce off, rather than hit the glass.

Landscaping With Native Plants On Spring Island

Coastal South Carolina is dotted with secluded island hammocks.  Many of them are pristine, or appear so.  Spring Island, near Beaufort and Hilton Head, is one.  The history of Spring Island is a fascinating tale of Indians, traders, antebellum life, Northern magnates and modern development, not unlike most of the Low-country.  But Spring Island is unique.  Carefully developed to preserve its natural beauty and seclusion, it's easy for the visitor to believe that nothing much has changed since the 1920s.

We arranged to meet with Thomas Angell of Verdant Enterprises, LLC. for a morning tour of a few of his projects on the island.  Thomas specializes in native plants, creative storm water management and imaginative landscape detailing with custom hardscape construction.

As we traveled down picturesque allees lined with magnificent live oaks, we were practically unaware of nearby residences screened from view by dense native plant growth.  Discrete address plaques barely hinted at what was hidden and growing behind those verdant garden walls.

Our first stop was at the residence of one of the area's leading proponents and experts of natural landscaping.  Unfortunately, she was away and unable to meet with us.  Thomas explained that her home was carefully sited to preserve the magnificent trees on the property, as well as to afford a splendid view of the river and marsh.  The structures do not appear to be imposed on the river bank, but to grow in harmony from it, surrounded by such local beauties as wax myrtle (Myrica cyrifera) and needle palm (Rhapidophyllum hystrix).

Both back and front of the home were beautifully landscaped exclusively with native species.  (You should know that the front of every waterfront home faces the water.  Arrival by land is through the back door. Whether through the front or back door, scrape your boots or shed them.)

An ancient oak provided shelter to blood-root (Sanguinaria canadensis), wild ginger (Asarum virginicum), trillium (T. maculatum), jack-in-the-pulpit (Arisaema triphyllum), indian pink (Spigelia marilandica), partridge berry (Mitchella repens), along with colonies of native grasses and ferns.

I was surprised to see the blood-root, wild ginger, trillium, jack-in-the-pulpit, and indian pink, but Thomas informed me that they are actually native to the area.  Botanist and nurseryman, Daniel Payne, owner of NatureScapes Of Beaufort, confirmed it.  Daniel arrived on site unexpectedly to inspect and maintain some of the plantings.  As we walked about, Daniel explained that Beaufort County is one of the most biologically diverse counties in South Carolina, and perhaps in the Southeast, with over 1597 naturally occurring native plant species inventoried to date.

The natural design was "civilized" with some of Thomas's hardscape detailing.  A local soft stone called hardpan was quarried for benches of serpentine or semi-circular patterns.  Because of its porosity, the hardpan was topped with laminated wood seating created by a regional craftsman.

As we toured the site, I commented on a native plant that, so far as I know, is never used elsewhere.  The common names are Devil's Grandmother or Elephant's Foot (Elephantopus tomentosus).  But Thomas had used it quite effectively.  The foliage is attractive, the flowers are charming, and, of course, it grows like a weed.  We agreed that sustainable landscaping using native materials requires that we try to see things through new eyes.  It's really not that difficult or new to see things afresh; all non-native ornamentals were originally weeds from elsewhere.

The owner, Thomas and Daniel had established a display garden nearby with various other native species, and a few regional "heirloom" plants on trial.  A "midden" constructed for the garden rose above a dry stream bed designed to collect and direct storm water to a bog garden.  A pool with flowing water provided habitat for native fresh-water aquatic plants, and also created a refreshing oasis of sight and sound.

Native landscaping involves philosophical discussion.  For example, one might wonder whether or when a native plant should be considered desirable.  Such is the case in this garden with poison ivy.  The typical reaction to poison ivy (Toxicodendron radicans) is to eradicate it.  But Daniel noted one specimen on the river bank which he allowed to remain.  The foliage, he explained, is quite colorful and attractive in the fall while the towering plant provides habitat and the seeds provide food for wildlife.  It grows at some distance from foot paths.  But then, the birds drop the seeds about the landscape to propagate more.  There comes a point when enough is enough and the solution calls for a squirt of herbicide.

Thomas was curious to take a look at some other projects he had completed several years ago.  A quick look now would prepare him for upcoming appointments with the owners.  It was disappointing to see that the plantings had not been properly maintained.  In my opinion, they demonstrated a lack of sensitivity on the part of some maintenance crews, or perhaps a lack of knowledge which can be remedied.  Expanses of lovely native grasses had been mowed like sod.  Soft cushions of billowing shrubs had been flattened at breast height like table tops.  Certainly, landscaping with native plants in naturalistic settings presents a new paradigm that must be studied carefully in order to maintain and appreciate.

Considering these examples of sustainable landscaping, one might assume that a naturalistic planting of native plants is by definition no-maintenance or low-maintenance.  That is not always true.  The level of maintenance depends, as with other types of landscaping, upon the form, function and appropriateness of the whole and its parts.  A building or structure may appear to be unified with the natural surroundings, but it is not actually, and nature is always on the move.  Sooner or later, considerable maintenance is in order.  Nevertheless, landscaping with native plants is a refreshing new concept which time has come.

Crocosmia - Bold, Beautiful, Easy To Grow

If the time has come for you to quit fussing over difficult plants, it's time for you to plant Crocosmia.  It's native to South Africa and northward to Malawi.  Crocosmia (pronounced kroh-KOZ-mee-uh) is a member of the Iridaceae family along with Gladiolus, Iris and Crocus.  The name, derived from Greek, means "smells like saffron" crocus.  There are about a dozen species, a few natural hybrids and about 120 cultivars.  Plant size ranges from 10" to 48" and more.  About a dozen flowers, carried on each long arching stem, may be yellow, shades of orange to red.  The colors are as hot as the bloom season: summer to fall.

Crocosmia's resemblance to gladiolus is unmistakable.  The sword-like foliage adds vertical emphasis to the garden while the bold, blazing flowers add drama.  Leaves may be evergreen or deciduous.

Corms produce more corms, and more and more, stacked on top of each other.  Older corms tend to be pulled deeper into the soil as the younger ones grow on top.  The arrangement looks like a chain of little biscuits.  The corms can be separated and replanted elsewhere.  Crocosmia also reproduces from seed.  Within a few seasons, you could have a dense bed of gorgeous, fiery blossoms.

They are superb for bulb borders, perennial gardens and even for naturalizing in meadows.  You can grow them in containers, too.  Tuck a few crocosmia corms anywhere you want a dash of color.  By the way, they attract lots of butterflies and hummingbirds!

Crocosmia normally thrives in USDA climate zones 6 through 9, so gardeners in most parts of the U.S. can enjoy them.  Some gardeners in climate zones 4 and 5 even report good success if the bed is mulched in winter.  Plant in full sun.  Average, well-drained garden soil with pH ranging from 6.1 to 7.8 is fine.

Before preparing your planting site, take a sample of your garden soil to your local Cooperative Extension Service office.  For a nominal fee, they will send the sample to a lab for analysis.  The analysis will normally be sent to you through the mail.  If the test results seem difficult to understand, don't hesitate to call your County Agent for explanation.

Crocosmia corms planted in fall will bloom the following year.  But the corms may also be planted in spring as you would gladiolus.  Unless you are naturalizing them in a meadow, prepare the planting bed by cultivating at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.

Your soil sample report will include soil amendment and fertilizer recommendations based upon the results of the test.  Follow them.  A fine all-around practice for bulbs is to mix 5 tablespoons of 10-10-10 fertilizer and 2 cups of bone meal per ten square feet area of bulb garden.  Repeat the application when growth appears, but be careful that fertilizer does not come into direct contact with plant tissue.

Crocosmia corms should be planted 3" deep.  Depth is measured to the bottom of the hole.  Recommended plant spacing is 6" to 10".

Crocosmia requires very little maintenance.  Plant them and forget about them.

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.

FAQ: A question about the length of muscadine grape vines

 Question:  I have several 2 year old muscadine vines that are producing well.  The vines hang to the ground.  Am I  supposed to keep the vines pruned back off the ground?

It doesn't hurt anything for the vines to hang to the ground.  They may get in the way of your lawn mower.  There's also the greater possibility for them to be sprayed if you apply herbicide under the vines to kill weeds.  Other than that, there's no harm in letting the vines grow to the ground.

On the other hand, if you wish to prune your vines to tidy up a bit, it won't hurt them in the least.  I suggest you prune them so that they hang no lower than your knees.  I'm assuming that you are growing them on a single wire trellis.

A Close Look At Echeveria


Take a walk in the countryside and look closely at what grows around you.  There are botanical wonders practically beneath your feet.  The best way to study a plant closely is to sense it as an artist.  It doesn't matter whether you think you are an artist.  Take time to discover it entirely.  You'll find that when you come to really know something as it is, your appreciation will grow immeasurably.


Atanasio Echeverría y Godoy was such an artist.  A native Mexican, he accompanied the Sessé and Mociño expedition through Mexico (1787-1803) to inventory the country's flora and fauna.  Echeverría's drawings and watercolors record the minutest details of his subjects with accuracy and sensitivity.  Plant species perhaps considered common by many he rendered notable.

Robert Runyon 1881-1968) was another artist who studied his surroundings meticulously.  A native Kentuckian, he moved to Texas in 1908 after the death of his wife.  By 1910 he had established himself in Brownsville as a successful commercial photographer, devoting his work to familiar subjects, souvenir photos for tourists, and photos of sensational events such as the Mexican Revolution.  Gradually his interest began to include indigenous plants.  He became an expert on the flora of northern Mexico and southern Texas.  In the early 1930s, he began to devote his energies to his interests as a naturalist and aspiring politician.  Runyon published two botanical works, Texas Cacti (1930) and Vernacular Names of Plants Indigenous to the Lower Rio Grande Valley (1938).  J. Frank Dobie, a folklorist and friend of Runyon, said of him, "You have to admire a man like Runyon, who cuts off a little hunk of the world and dedicates a lifetime to its study."

It's fitting that plants of the region bear the names of Echeverría and Runyon.

The genus, Echeveria (pronounced ech-eh-VER-ee-ah), includes about 40 species of plants native to Mexico, Central America and parts of South America.  They are characterized by their thick, succulent leaves arranged in rosettes.  The leaves store water, so they're very drought tolerant. They grow quickly in full sun and in almost any soil type as long as it is slightly acidic or neutral and well-drained.  Sandy or rocky soil is perfect.  The common name, "Mexican Hens-and-chicks", was given because of the plants resemble Sempervivum, which is also called "Hens-and-chicks."  Smaller plants (chicks) that are produced on short side-shoots are clustered very close to the parent plant.

The species bearing Runyon's name is E. runyonii (pronounced run-YON-ee-eye), one of the more attractive and popular members of the genus.  E. runyonii 'Topsy Turvy' is a choice variety.

Echeverias thrive in difficult, dry areas.  Hardiness varies, but they are generally much less cold-hardy than Sempervivum, surviving in USDA climate zones 8 or 9 through 11.  They vary in foliage shape, color and growth height.  Tubular flowers are produced from summer to fall on succulent stems.  Hummingbirds love them.

They are are often used as edging plants, in rock gardens, and in containers.  Gardeners in colder regions can grow them successfully indoors.  Being drought-tolerant, they are excellent for xeriscaping.

Plant Echeverias about 10” to 15" apart in well-drained soil with pH ranging from 5.6 to 7.5.  To determine whether your soil is hospitable, take a sample to your nearby Cooperative Extension Service office for analysis.

Pint-sized plants usually produce a few "chicks" within the year.  They may be divided and replanted every few years to maintain compactness.  Some species benefit from light applications of a balanced fertilizer.  Let the ground dry between irrigation.

Echeverias are fascinating plants to the eye and to the touch.  With so many ways to grow them, any gardener can find a place to use and enjoy them.

FAQ: What is xeriscaping?

"Xeriscaping" is a blend of two words to combine their meanings into one concept.  "Xeri" is derived from the Greek word, xeros, meaning dry.  "Scaping" is derived from the word "landscaping."  So the blended word describes a manner of gardening that reduces or eliminates the need for supplemental watering.  Xeriscaping is appropriate for regions that are naturally dry, for areas under water-use restrictions, and for those gardeners who simply want to reduce the expense or environmental impact of additional water use.

"Xeriscaping" is often associated with the accompanying logo.

FAQ: How far apart should ground cover junipers be planted?


Q.  We have a part of a lawn with about a 30 degree slope (approximately 420 sq ft) that we are considering putting juniper ground cover on. How far apart should the junipers be planted to ultimately cover completely? And can we put down a garden cloth to  keep weeds at a minimum?  We are looking for maintenance free as  much as possible.

A. Planting distance is relative. Depends upon the habit of the species, how soon you want them to completely cover, how much you wish to spend and/or your level of patience. Species with slower growth rates and compact habits such as J. procumbens 'Nana' may be planted 36" apart. J. horizontalis may be planted 48" apart or more. If you're in a big hurry, plant closer.

You asked about ground cover fabric.  I'm not a fan of it for various reasons.  During hard rain, the water can't perk through quickly enough, so the water tends to flow off in sheets carrying mulch, etc. with it.  Ground cover fabrics usually don't bio-degrade.  The edges of fabrics tend to become exposed, look sloppy, and often end up wrapped in your mower blades.  Ground cover fabrics (weed barriers) may prevent weeds from coming up through them, but often do not prevent weed seeds from germinating and sending their
roots downward.

Bark and wood mulches on slopes tend to wash away with heavy rains.  I recommend 3" or more of straw mulch rather than bark/wood mulch and ground cover fabric.  Water perks downward through it quickly.  (Burlap spread atop straw mulch may help to stabilize it.  I realize that burlap may not be aesthetically pleasing.) The straw will need to be replenished occasionally, but it's cheap.  When your junipers mature and cover the slope, you can dispense with the straw mulch and burlap.

Maintenance free is good!

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."

Scabiosa: Better Than Its Name Sounds


Whether it is pronounced SCAB-ee-oh-sah or SKAY-bee-oh-sah, Scabiosa sounds dreadful and makes me imagine an itch coming on.

When I was a child, head lice and scabies struck fear in the heart of my mom.  Scabies is a skin condition caused by a tiny mite (Sarcoptes scabiei var. hominis) tunneling under the epidermis to lay its eggs.  Head lice and scabies were socially delicate matters in those days and very difficult to eradicate.  Among the many things I was warned to avoid at school and elsewhere, other boys' hats and people with rashes were near the top of the list.

I didn't obey all of her warnings.  I wore a yarmulke (kosher enough I thought) borrowed from Larry so I could join his middle-school entourage, and rassled with a scabious assailant when he wouldn't let go of my leg.  I ran over oyster shells, brushed by poison ivy, boated without a shirt, and explored island hammocks, so I've had my share of wounds, rashes, sunburns, itches and chiggers, but never head lice or scabies.

It's said that Scabiosa was named by Carl Linnaeus because of its traditional use as a treatment for scabies.  Perhaps Scabiosa and other herbs were steeped as tea in a tub of water for bathing, or the rough leaves might have been used to scratch the itch.  I don't know that it actually works for I've never had to use it.

The genus contains from 14 to 80 species (depends on who's counting what) native to Europe, parts of Asia and the Mediterranean region.  However, some have been introduced to North America.  Scabiosa is a member of the Dipsacaceae family.   A common name for it is Pincushion Flower, derived from the appearance of the seed head.

Very few scabiosas are used as ornamental plants.  Most are from the species, S. columbaria (pronounced kol-um-BAR-ee-ah).  Columbaria means "pigeon-like", perhaps because it can be found living in niches on the sides of cliffs in its native habitat.

A cultivar, S. columbaria 'Butterfly Blue' was named Perennial Plant Of The Year in 2000 by the Perennial Plant Association.  Since then its popularity has taken off.  Light blue flowers are produced in mid-summer on mounding plants up to 18" high.  Flowering may be extended through fall if the spent seed heads are removed.  In addition to blue, other cultivars exhibit flowers in pink and white.  Scabiosa is great for naturalizing, growing in perennial gardens, mixed gardens with bulbs and annuals, and in low borders.  Butterflies love it, and birds love the seeds.  It's easy to care for and drought-tolerant when established.

S. columbaria thrives in USDA climate zones 4 through 9 or 10.  Plant in full sun to partial shade.  Average well-drained garden soil with pH ranging from 6.6 to 7.8 is fine.

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 and 2 cups of bone meal per ten square feet area.  Repeat the application later in the season if they appear to need a boost, but be careful that fertilizer does not come into direct contact with plant tissue.

Scabiosa is much better than its name sounds.  Plant it in your garden and you'll soon understand why it has become so popular.

FAQ: Can I transplant junipers? When is the best time?

Q.  I have had junipers planted for a couple of years.....is it possible to move them to a different area of the yard?  Is there a certain time of year I should do this?

A. It is possible to move your junipers to a different area of the yard.  The chance of success varies according to the season of the year and the size of the plants.  It's best to try moving them during the cooler months.

When transplanting, you must keep as much soil intact around the roots as possible.  You may wish to move them yourself.  If not, perhaps a local nursery can assist you.

You did not indicate the species or size of the junipers.  If they are low-growing, you'll need some baling twine to tie the branches upward.  I'll assume that the trunk of the plant is 1" diameter measured about 6" above the soil line.

You will also need a flat-bladed spade with a sharp edge, a square sheet of burlap about 48" x 48", a dozen or more nails (10D, 3").

Your objective will be to form a root ball, move the entire shrub with root ball intact from the ground, place it on the burlap square, wrap the burlap around the root ball, secure it, and transport the shrub ball and burlap to its new location.

The root ball should be 12" in diameter for each 1" diameter of the plant trunk.  Begin by scraping weeds, grass and dirt from around the plant, exposing what will be the top of the root ball.

To form the ball, carve a shallow trench with the corner of your spade around the perimeter at the proper distance from the trunk.  With our example, the distance from the trunk should be about 12" radius.  Now, with the front of the spade facing you, begin digging the trench wider and deeper.  Shape the top of the soil into a ball by pulling soil with the spade away from the trunk and toward you.  Work your way around the plant.  Carve the trench more deeply as you go, remove excess soil.  Continue to work your way around the plant, repeating the steps until 1/2 of a ball has taken shape.  Visualize a small beach ball, if it helps.  When 1/2 of the ball has taken shape, begin carving gradually under the ball.

When you've formed about 3/4 of a ball, begin forcing the spade under the ball at an angle as you continue to work your way around the ball.  Be careful not to disturb the soil in the ball.  You don't want it falling apart.

When the ball is completely severed, you may remove the ball from the soil.  I recommend you slide the spade under the ball, leverage the ball up onto the spade and gently slide the spade with the plant out of the hole.

Slide the spade and root ball onto the burlap square.  Position the ball with the plant upright in the center of the square.  Remove the spade.  Pull the opposite corners of the burlap toward the trunk and tie them tightly.  Open gaps in the burlap may be pinned to close with the nails.  Special nails are made for the purpose, but 10D 3" nails should do.  Take care when pressing the nails through the fabric.  Wear gloves to protect your fingers.

Unless you are replanting immediately, cover the wrapped root ball with soil or mulch and keep it moist.

When replanting, the new planting hole should be the same depth as the original hole, but twice as wide.  When positioned in the hole, the top of the root ball should be at the same level as the surrounding soil.  DO NOT REMOVE THE BURLAP!  With some of the excess soil, form a ring about 5" deep around the hole and pack it tightly.  Place the end of a water hose inside the soil ring at the edge of the hole with the water running gently.  Keep the plant upright and back-fill the hole with original soil.  The water and soil will form a slurry of mud.  Then continue to back-fill the hole.  When the fill has reached the top of the root ball, stop back-filling and turn off the water.  Allow the soil to settle.  If necessary, add more soil around the root ball.  DO NOT COVER THE ROOT BALL WITH ADDITIONAL SOIL. 

If your plant is tall and located in a windy area, it may require bracing.  In most cases it will not.  At any rate, that is a subject for another day.

How I Love My Santolina



Santolina, Santolina,
How I love my Santolina,
Some are green and some are gray,
Rub them each and every day
It's amazing -- you will praise them
As they chase the bugs away.

I'm not sure who composed that poem, but it appeared on an advertising leaflet from noted herbalist Sal Gilbertie.  The poem has it right.  Santolina is a very effective insect repellant.

Santolina (pronounced san-toh-LEE-nah) is a genus in the Asteraceae family which also includes ageratum, asters, daisies, goldenrod, sunflower and yarrow.  There may be up to two dozen species in the genus.

The name, Santolina, means "holy flax", but it seems no one knows why.  The plant was well-known in ancient times for its medicinal and insect-repellant properties.  Flax, of course, is a plant of a different genus used for fiber.  The Shroud of Turin has been called The Holy Flax of Passion, but I can find no indication why the genus bears the name.  I suppose the name is lost in etymological obscurity.

Native to the  Mediterranean region, santolina plants are generally evergreen in mild climates.  They prefer dry, poor, sandy soils, full sun, low humidity, and tolerate heat and drought very well.

Santolina species have been popular as low hedges for traditional knot gardens. They are also used in wreaths and potpourri. From the Middle Ages until the 18th century, santolina was strewn on the floor as an insect repellent, disinfectant, and to cover odors.  The flowers and seeds were used to treat intestinal parasites.  Pliny, the Roman naturalist, prescribed wine containing santolina for snake bites.

My favorite species is Santolina rosmarinifolia.  Mature height is 12" to 24".  It spreads in a mound shape to 24" to 48".  The plant is great for herb gardens, fragrance gardens in hot, dry climates.

S. rosmarinifolia is hardy in USDA climate zones 7 - 10.  It prefers well-drained soil.  Soil pH should range from 6.6 to 7.8.  Take a soil sample to your nearest Cooperative Extension Service office for proper analysis.  Follow the recommendations.

Cultivate at least 6" deep, removing all traces of weeds. Compacted soil should be cultivated to 10" deep.

Space plants 36" to 48" 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 santolina with other species having similar cultural requirements.  It has no insect problems and few disease problems.  The greatest cause of failure is over-watering.  Allow soil to dry between watering.

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.
