Daylily

Small Gardens Mean Fewer Colors

To keep a small garden from looking chaotic, show restraint with the number of flower colors. Smallish gardens can look fabulous with only two colors. This is not to say only two types of plants. Yellow and purple flowers pair well and give the gardener a large number of choices. Repeating the same flower colors but using different sizes of blooms and leaf forms provides attractive contrasts. Because flowers bloom on their own timeline, the use of different plants with the same bloom shades will keep the garden colorful even if some of them are taking a blooming siesta.

For my own small courtyard garden, I decided all perennials and flowering shrubs would be in shades of yellow, coral, and purple. To lure pollinators, I included yellow goldenrod (Solidago) and brown-eyed Susans (Rudbeckia triloba) in the dryest area, and yellow rain lilies in the damp areas near the drainage catch basin. For coral shades, I used Drift roses (small, shrubby, lower maintenance than most roses), coral penstemons, a dwarf Red Hot Poker (Kniphofia ‘Poco Red’) which is more coral than red, and a couple unknown varieties of daylily. For the purples, I chose sterile, dwarf Pugster® butterfly bushes (Buddleia), purpleheart (Tradescantia), purple coneflowers (Echinacea purpurea), and lavender-flowered Society Garlic (Tulbaghia violacea). All these plants attract numerous butterflies and hummingbirds.

I wasn’t certain that the Cuphea ‘Candy Corn’ that I planted last year would overwinter, but they did and now the yellow and orange flowers look right at home between the corals and yellows. The Gaillardia ‘Spin Top Red’ I planted last fall is more red than coral, but it has bloomed so lavishly that it will remain. Several varieties of Calla lilies in the chosen colors have not begun flowering yet.

This being a first-year garden, there were a number of empty holes in the layout, so I started annuals from seed to fill in the gaps. Next year, those gaps will be smaller as the shrubs and perennials gain size. By year three, annual use will be at a minimum. For now, yellow Melampodium, coral Zinnia, coral Salvia, purple Gomphrena and purple Salvia are providing abundant color. These were chosen not only for their hues but because they flower like mad all summer long and require little in the way of maintenance, other than the occasional removal of spent flowers (Zinnia and Salvia).

My past gardens have never featured coral shades, but I’m loving this color in the new beds. Plans are underway to add peachy/coral shades of Yarrow, Alstroemeria, Lycoris (“Hurricane Lily”), and Chrysanthemum to extend the chosen color palette into autumn. I’m including a few photos of the coral plants.

Don't Disrespect Ditch Lilies

“Familiarity breeds contempt.” Or so said Geoffrey Chaucer in one of The Canterbury Tales. Perhaps that is why people hold the common orange day-lily, Hemerocallis fulva, in disdain. This “Ditch Lily” was a favorite of southern farmers’ wives in the 1950s and 60s, who prized their showy blooms and ease of growth. It is this effortless growth and rapid multiplication that causes concern. They “have the potential to become invasive,” per Invasives.org.

The common, orange Ditch Lily occurs in every eastern state. Like other members of the day-lily family, they thrive in full sun and prefer a slightly acidic, well-drained soil. They can be used instead of shrubs as a short hedge. They can also be used as a groundcover on slopes where mowing is impractical, and do a super job of preventing erosion. Ditch Lily flowers last only a single day, but they produce many, many buds so the bloom show goes on for weeks. Once all the buds on a stem have flowered, the naked stem can be removed to prevent seed formation and to make the plant look neater. This may encourage additional flowers.

Hybridizers have produced new colors, shapes, and forms of day-lilies. Colors have reached beyond the common orange to encompass all the warmer shades of the color wheel, from yellow to deep red or even purple, and everything between. Flowers are double, striped, freckled, curved. Some of these are highly valued (read: expensive). I particularly liked those with thick, ruffled petal edges until I heard a plantsman describe it as “chicken fat.” Now, I think of Tyson whenever I see those.

Whether your day-lilies are of the dug-it-from-the-roadside variety or one of the exorbitant specialty type, strands of the long grass-like foliage wilt and brown during the growing season. Growers advise us to remove the dead leaves as they occur, and cut off all the dead foliage once it is winter-killed. Rather than grooming my plants regularly to keep them neat, I follow a more radical (tough love) approach. Once half the foliage has browned, I gather it into a ponytail and decapitate it, leaving about four inches of leaf above soil level. Then I give the pruned plant a dose of liquid fertilizer. While plants will not repeat bloom, they do throw new foliage which is fresh-looking all the way to frost. I have not noticed a reduction in plant vigor as a result of this treatment.

Congested day-lily plants will have fewer flowers. To remedy, lift the entire clump, divide them and replant into amended soil. In fertile soil with plentiful water, you may need to divide every other year or every third year. When you lift a mature clump, you will find that it has formed a series of fleshy tubers, almost like a Dahlia. All divisions should have some of these little taters. After a vigorous division several years ago, I swept the damaged pieces off my garden bench into a bucket that contained discarded potting soil from a spent planter. Several weeks later, I discovered that each of the small bulbs had sprouted new leaves and roots. They are definitely survivors.

Day-lilies are drought-tolerant once established, and not prone to damage from insects or disease, although day-lily rust or leaf-streak may appear, as well as damage from thrips or slugs. Deer find the flowers and leaves quite tasty. I understand that day-lily flowers are edible, but have never sampled them. I prefer to enjoy them in the flower border – whether they are the high-dollar, super-hybridized variety, or the simple, old-fashioned orange Ditch Lily.
