Hemerocallis, the generic classification of daylilies, means ‘beauty for a day.’ Each flower only lasts a day, but there are many buds to open on multiple stalks, or scapes, for a long succession of bloom. And though daylilies are called “lilies,” they are not true lilies, but grow from tough, fibrous roots rather than bulbs like true lilies.
Are daylilies the ideal perennial? They are certainly very versatile. They can be used in mass groupings, or as individual specimens in the mixed perennial border. They come in many sizes from tiny miniatures to large blooms of over 5” wide. They have varied forms from the simple shapes of the species, to extremely ruffled, to elongated spidery shapes, and they are easy to grow, reliable and beautiful. The grassy foliage is neat and attractive all season, and they have few insect or disease problems.
The color range is astounding from near white, cream, melon, orange, pink, rose, red, purple, wine to almost black. The only colors eluding hybridizers are true white and blue—and they will probably achieve those. And the patterns and color combinations of recent introductions are incredible. It’s hard to imagine that all this variation has come from crossing a few species, and then re-crossing selected cultivars. No wonder daylily hybridization is so popular! Everyone wants to find that next breakthrough.
Some daylilies are quite fragrant, adding to their charm. All parts of the plant are edible, too—they have been used as a food source in Asia for centuries.
The ranking of diploid or tetraploid refers to the genetic makeup of a particular cultivar.
Diploid means that there are two sets of chromosomes in each cell. Diploids make up the majority of daylilies and are said to be easier to cross.
Tetraploid means that the cultivar has four sets of chromosomes in each cell causing sturdier growth, larger flowers, more budscapes and greater vigor.
There are thousands of cultivars available in almost any size, shape and color to work with any garden scheme or location. To choose your favorites, visit local garden centers, botanical gardens, online specialists, and daylily growers at the peak of bloom. For more information, the American Daylily Society has an excellent, information-packed website, www.daylilies.org.
Hemerocallis fulva, tawny or orange daylily, Zones 3-9. This is a common sight along roadsides, giving it the epithet of "ditch lily." But it doesn't deserve the scorn, being pretty in its own right, and tough. Settlers brought it to the colonies where it escaped cultivation and established colonies readily. Good for erosion control and a pollinator attractant.
Hemerocallis fulva ‘Kwanso,’ double daylily, Zones 3-9. The double form of H. fulva, has been used in the hybridization of fancy modern double cultivars.
Hemerocallis lilioasphodelus, lemon lily, Zones 3-10. The lemon daylily was beloved by early North American settlers for its dependability and fragrance. Today it is used in breeding new cultivars with an early blooming habit and excellent fragrance.
