There comes a moment in spring when the garden seems determined to spend everything it has.
The tentative flowers of early spring are behind us. Trees have begun to leaf out, the days are warmer, and borders that only weeks before seemed almost empty are filling rapidly with green. Then, just when the traditional tulip season might appear to be drawing toward its close, the Double Late tulips arrive.
And they do not arrive quietly.
With enormous, many-petaled flowers in shades of rose, pink, red, purple, yellow, cream, white and combinations of several colors, Mixed Double Late Tulips can transform an ordinary spring border into something extravagant. Their flowers are so full that they are frequently called peony-flowered tulips, and when planted in a generous mixture, they create the impression of an old garden overflowing with flowers accumulated through generations.
There is something wonderfully romantic about them.
Perhaps that is because no two corners of a mixed planting look quite the same. Perhaps it is because their great flowers seem almost too elaborate for tulips. Or perhaps it is simply because they bloom at that fleeting moment when spring has reached its fullness and summer is waiting just beyond the garden gate.
What Are Double Late Tulips?
Double Late tulips are a distinct class of garden tulips characterized by their large, densely petaled flowers and comparatively late flowering season.
An ordinary single tulip has six tepals arranged in the familiar cup. Double tulips possess many more.
The result can be extraordinary.
A fully opened Double Late tulip may scarcely resemble the simple wild tulips from which centuries of cultivated varieties ultimately descended. Instead, its layers of petals form a broad, rounded flower reminiscent of a peony or old-fashioned garden rose.
This resemblance has given the group its familiar alternative name: peony-flowered tulips.
Plants generally grow about 16 to 24 inches tall, depending upon the varieties included in the mixture. Their flowers are substantial and are carried above broad, blue-green to fresh-green foliage.
And substantial is not an exaggeration.
When fully open, some Double Late flowers can reach roughly four inches across or more. A mature planting in full bloom has a richness that few other tulip classes can equal.
The Last Great Tulip Show of Spring
The word "Late" in Double Late is important.
These tulips generally flower toward the end of the tulip season, often from late April into May, depending upon climate and weather.
That makes them tremendously useful.
A garden planted only with one class of tulips may produce a magnificent display for a short period and then suddenly be finished. But by combining early, midseason and late tulips, the performance can continue for weeks.
Double Late tulips provide the finale.
And what a finale it is.
By the time they flower, the garden around them is considerably greener than it was when the earliest tulips appeared. Emerging perennials and shrubs provide a lush background for the great double blossoms.
They do not seem to announce that spring has begun.
They proclaim that spring has reached its height.
Double Tulips Have Been With Us for Centuries
The idea of a double-flowered tulip is by no means modern.
Tulips with multiplied petals were already known in European cultivation during the seventeenth century, the great age of Dutch enthusiasm for the flower. Double-flowered forms appear in early tulip classifications and period illustrations, evidence that gardeners prized their extraordinary fullness almost from the beginning of Europe's long love affair with tulips.
The modern Double Late class developed from later generations of breeding and selection, particularly from the old late-flowering double tulips sometimes historically associated with the Peony-flowered group.
So while the particular cultivars available today may be comparatively recent introductions, the gardener who plants double tulips is participating in a horticultural tradition several centuries old.
That seems appropriate.
There is something decidedly old-world about a great double tulip.
A modern landscape can certainly accommodate them, but they look equally convincing beside an old brick walk, spilling through a cottage border or flowering near a weathered garden gate.
They carry a little of the old Dutch garden with them.
Why Plant a Mixture?
There are times when planting a single tulip cultivar in a great disciplined sweep is exactly right.
Mixed Double Late Tulips offer something entirely different.
Instead of a uniform block of color, a mixture creates a changing tapestry.
One flower may be deep burgundy.
Beside it stands another in shell pink.
Beyond that is cream, yellow, scarlet, white or lavender-purple. Some may be solid colors while others can be streaked, edged, flushed or feathered with contrasting shades.
The eye moves constantly through the planting.
That makes a mixture especially effective in gardens intended to look abundant rather than regimented.
The Delight of Not Knowing Exactly What Will Appear
There is also a small pleasure in planting a mixture that disappears completely underground for winter.
You know tulips will emerge.
You know they will be double.
But you don't know precisely where each color will appear.
Autumn conceals the arrangement.
Winter keeps the secret.
Then spring reveals it.
A pink flower appears here. A dark one opens there. A yellow bud begins showing color somewhere you had forgotten planting anything at all.
It is one of the few occasions in gardening when uncertainty is part of the attraction.
A gardener spends enough time trying to control things.
Sometimes it is pleasant to plant the bulbs and allow spring to arrange the bouquet.
A More Natural Garden Effect
Mixed colors also help a tulip planting feel less like a bedding display and more like part of the garden itself.
Uniform plantings have their place, particularly in formal landscapes. But in cottage gardens, mixed borders and informal settings, an assortment of colors can blend more naturally with the plants already present.
The trick is to plant enough bulbs.
Scattering ten Double Late tulips over a large border may simply make them look lost.
Planting thirty, fifty or a hundred in generous groups produces something quite different.
The colors begin to repeat.
One pink flower answers another several feet away. White appears here and then again farther down the border. Dark purple provides occasional depth. Yellow catches the sunlight.
The mixture gains unity without becoming uniform.
Plant in Drifts, Not Rows
For an informal garden, resist the temptation to line the bulbs up like soldiers.
Instead, plant them in broad, irregular drifts.
One useful method is simply to mix the bulbs before planting and distribute them naturally through the chosen area. Avoid trying to arrange the colors individually. Part of the beauty of a mixture is allowing chance to create combinations you might never have planned.
Plant some groups more densely and allow others to thin toward the edges.
The finished planting should appear to flow through the border rather than occupy a rectangle within it.
Nature is rather fond of irregularity.
Gardens usually benefit from borrowing some.
Perfect for the Cottage Garden
Mixed Double Late Tulips seem almost made for a cottage garden.
Plant them among emerging perennials where their great flowers can rise through fresh spring foliage.
Peonies make particularly appropriate neighbors. The tulips flower as the peony plants are developing, and the visual relationship between a double tulip and the great flowers that will follow is delightful.
Hardy geraniums, catmint and other perennials can also surround the bulbs. As these plants expand later in spring, they help conceal the tulip foliage as it begins to yellow.
The tulips have their moment.
Then the perennial garden takes the stage.
Magnificent Along a Garden Walk
Double Late tulips deserve to be seen closely.
Their flowers contain far more detail than can be appreciated from across a lawn. Layers of petals fold over one another, colors deepen toward the centers, and some varieties change subtly as their blossoms mature.
Planting them beside a walkway allows you to enjoy those details.
It also lets the flowers spill visually toward the path, creating that wonderfully abundant impression of an old garden slightly too full of beautiful things.
There are worse faults for a garden to have.
A Romantic Planting Beneath Roses
Mixed Double Late Tulips can also be planted among roses.
When the tulips are flowering, the roses are generally developing rapidly but have not yet reached their summer glory.
The tulips provide the color first.
As their flowers fade, the roses begin taking over.
Meanwhile, expanding rose foliage helps distract attention from the declining tulip leaves.
This succession is one of the oldest and best principles of ornamental gardening: don't ask one plant to provide everything.
Allow one season to hand the garden to the next.
Wonderful With Old Houses
There is something particularly attractive about mixed double tulips near traditional architecture.
Plant them along an old brick walk.
Place them beside stone steps.
Let them fill a bed beneath a white picket fence.
Use them around a porch or near an old garden bench.
Their great peony-like blossoms possess enough formality to complement architecture, while the mixture of colors keeps the planting from becoming stiff.
Against weathered brick, aged wood or old stone, they can look as though they have been flowering there for generations.
That illusion is worth cultivating.
Plant Them in Containers
Mixed Double Late Tulips can make spectacular container displays.
A large pot filled with a mixture becomes a ready-made spring bouquet.
Because the flowers are large, choose a container substantial enough to balance them visually. Broad terracotta pots, urns and traditional planters work especially well.
Plant generously.
Tulip containers are not the place for excessive economy. Closely planted bulbs produce the lush display we are after.
When several colors begin opening together, the pot can resemble an enormous floral arrangement that happens to be growing from the soil.
Place it near an entrance or terrace where the flowers can be enjoyed every day.
The Perfect Cutting-Garden Tulip
If you enjoy bringing flowers indoors, Mixed Double Late Tulips are difficult to resist.
Their long stems and peony-like blossoms make them magnificent cut flowers.
And a mixture gives you an assortment of colors without requiring a separate row of every cultivar.
Cut a few pinks.
Add a white.
Perhaps a deep purple and a pale yellow.
Suddenly you have a spring bouquet that looks as though it came from a florist who had been given very generous instructions.
Or use one color alone.
A vase containing five great double white tulips can be just as beautiful as an elaborate mixed arrangement.
A Word About Those Enormous Flowers
The very characteristic that makes Double Late tulips spectacular can occasionally make them vulnerable.
Those flowers are heavy.
After a hard spring rain, the petals can hold considerable water. Strong wind combined with wet flowers may bend or break stems.
For that reason, plant them where they have some protection from the worst winds if possible.
A sheltered border, courtyard garden or area near a hedge can be ideal.
This is not a defect peculiar to tulips. Large flowers throughout the garden pay a price for magnificence.
A peony after a thunderstorm understands the situation perfectly.
Growing Mixed Double Late Tulips
Plant the bulbs in autumn after the soil has begun to cool.
Choose a location receiving plenty of sun and having fertile, well-drained soil. Tulips need moisture while actively growing, but they strongly dislike waterlogged ground.
Planting bulbs approximately 6 inches deep is suitable in many garden soils, with somewhat deeper planting sometimes useful in lighter soils or colder climates.
For landscape groups, bulbs can generally be spaced about 4 to 6 inches apart, although closer planting creates a more concentrated first-year display.
Then wait.
Autumn planting is an act of faith peculiar to gardeners. We bury something brown and apparently lifeless just as the garden is dying back, cover it with cold earth, and trust that spring will remember where we put it.
Usually, it does.
Let the Foliage Finish Its Work
After flowering, Double Late tulips leave behind the same problem as every other tulip: foliage that becomes progressively less attractive.
Leave it alone.
The leaves need sunlight to manufacture and store energy in the bulb. Cutting green foliage immediately after flowering weakens the bulb and reduces its chance of flowering well again.
Instead, remove the spent flower heads and allow the foliage to yellow naturally.
This is another reason to grow the bulbs among perennials. As neighboring plants expand, they gradually conceal the fading tulip leaves.
Good planting design can hide a multitude of horticultural necessities.
Will They Return?
Double Late tulips may return in subsequent years when conditions suit them, but they should not be expected to naturalize with the enthusiasm of daffodils or some species tulips.
Excellent drainage, abundant sunlight and allowing the foliage to mature fully will improve their chances.
Even when some bulbs gradually decline, the first great spring display can make the planting worthwhile.
And when a clump does return and flower again, it feels less like something purchased and more like something that has become part of the garden.
Why Mixed Colors Work So Well
Perhaps the strongest argument for a mixture is that spring itself is mixed.
Look at an old garden in April and May.
There isn't one shade of green but dozens. Azaleas bloom beside dogwoods. Roses are beginning while narcissus are finishing. Violets appear beneath shrubs. New leaves are bronze, chartreuse, emerald and gray-green.
Mixed Double Late Tulips belong naturally to that abundance.
Their colors don't need to match perfectly.
They need to converse.
Pink beside purple.
Yellow beside white.
Red emerging through green leaves.
A pale flower catching the last light of evening while a dark one disappears into shadow.
That variety gives the planting life.
The Grand Finale
Mixed Double Late Tulips are flowers for gardeners who believe spring ought to finish generously.
Their ancestry reaches back through centuries of fascination with double-flowered tulips, to a time when European gardeners were already marveling at tulips transformed by extra petals into flowers resembling roses and peonies.
Today they offer the same pleasure.
Plant them in broad drifts through a perennial border. Let them wander beneath roses. Fill great pots beside the front steps. Grow enough to cut armfuls for the house.
And don't worry too much about which color will appear beside which.
There is a certain romance in surrendering that decision to chance.
All winter the bulbs lie unseen beneath the earth. Then, late in spring, they rise together—pink, crimson, purple, yellow, white, cream and all the shades between—until the garden looks less like something carefully decorated and more like something celebrating.
And perhaps that is the real appeal of Mixed Double Late Tulips.
By the time they flower, spring has nothing left to prove.
It can simply be beautiful.
