A daylily, day lily or ditch-lily is a flowering plant in the genus ''Hemerocallis'' , a member of the family Asphodelaceae, subfamily Hemerocallidoideae, native to Asia. Despite the common name, it is not, in fact, a lily, nor does it specifically grow in ditches. Gardening enthusiasts and

Taxonomy

Despite their common name, daylilies are not true lilies (plants from the genus '' Lilium'', family Liliaceae). Although the flowers of ''Hemerocallis'' and ''Lilium'' species have a similar shape, their growth habits, stems and leaf shapes are distinctive. Before 2009, the scientific classification of daylilies put them into the family Liliaceae. In 2009, under the
APG III system The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a fur ...
, daylilies were removed from the family Liliaceae and assigned to the family Xanthorrhoeaceae, subfamily Hemerocallidoideae. Xanthorrhoeaceae was renamed in 2016 to Asphodelaceae in the APG IV system

Etymology

The name ''Hemerocallis'' comes from the Greek words (''hēmera'') "day" and (''kalos'') "beautiful".


Distribution and habitat

''Hemerocallis'' species are native to Asia, primarily eastern Asia, including

and southern Siberia. This genus is popular worldwide because of the showy flowers and hardiness of many kinds. There are over 80,000 registered cultivars. Hundreds of cultivars have fragrant flowers, and more scented cultivars are appearing more frequently in northern hybridization programs. Some earlier blooming cultivars rebloom later in the season, particularly if their capsules, in which seeds are developing, are removed. Daylilies have been found growing wild for millennia throughout China, Mongolia, northern India, Korea, and Japan. There are thousand-year-old Chinese paintings showing orange daylilies that are remarkably similar to the flowers that grace modern gardens. Daylilies may have been first brought to Europe by traders along the silk routes from Asia. However it was not until 1753 that daylilies were given their botanic name of ''Hemerocallis'' by the Swedish naturalist Carl Linnaeus. Daylilies were first brought to North America by early European immigrants, who packed the roots along with other treasured possessions for the journey to the New World. By the early 1800s, the plant had become naturalized, and a bright orange clump of flowers was a common sight in many homestead gardens. The orange or tawny daylily (''

Cultivation

As popular as daylilies were for many hundreds of years, it was not until the late 19th century that botanists and gardeners began to experiment with hybridizing the plants. Over the next hundred years, thousands of different hybrids were developed from only a few wild varieties. In fact, most modern hybrids are descended from two types of daylily. One is ''Hemerocallis flava''—the yellow lemon lily. The other is ''Hemerocallis fulva'', the familiar tawny-orange daylily, also known affectionately as the "ditch lily". The daylily has been nicknamed "the perfect perennial" by gardeners, due to its brilliant colors, ability to tolerate drought and frost and to thrive in many different climate zones, and for being generally low maintenance. It is a vigorous perennial that lasts for many years in a garden, with very little care and adapts to many different soil and light conditions. Daylilies have a relatively short blooming period, depending on the type. Some will bloom in early spring while others wait until the summer or even autumn. Most daylily plants bloom for 1 through 5 weeks, although some bloom twice in one season ("rebloomers)". Daylilies are not commonly used as cut flowers for formal flower arranging, yet they make good cut flowers otherwise, as new flowers continue to open on cut stems over several days.

plants. Hybridizers have developed the vast majority of cultivars within the last 100 years.

has been a specialty in the United States, where daylily heat- and drought-resistance made them garden standbys since the 1950s. New cultivars have sold for thousands of dollars, but many sturdy and prolific cultivars sell at reasonable prices of US$20 or less. ''Hemerocallis'' is one of the very highly hybridized plant genera. Hybridizers register hundreds of new cultivars yearly. Hybridizers have extended the genus' color range from the yellow, orange, and pale pink of the species, through vibrant reds, purples, lavenders, greenish tones, near-black, near-white, and more. However, hybridizers have not yet been able to produce a daylily with primarily blue flowers. Flowers of some cultivars have small areas of bluish shades, particularly in the eyezones. Other flower traits that hybridizers developed include height, scent, ruffled edges, doubling, contrasting "eyes" in the center of a bloom, fringed edges called ‘teeth’, and an illusion of glitter called "diamond dust". Sought-after improvements include rust resistance, foliage color, variegation, plant disease resistance, and the ability to form large, neat clumps. Hybridizers also seek to make cultivars cold-hardier by crossing evergreen and semi-evergreen plants with dormant varieties. In recent decades, many hybridizers have focused on breeding tetraploid plants, which tend to have sturdier scapes and tepals than diploids, as well as some flower-color traits that are not found in diploids. Until this trend took root, nearly all daylilies were diploid. "Tets," as they are called by aficionados, have 44 chromosomes, while triploids have 33 chromosomes and diploids have 22 chromosomes per individual plant. Diploid and tetraploid daylilies cannot be crossed to produce new cultivarsDaylilies

s) and dividing groups by gardeners. A polymerous daylily flower is one with more than three sepals and more than three petals. Although some people synonymize "polymerous" with "double", some polymerous flowers have as many as twice the normal number of sepals and petals. Formerly daylilies were only available in yellow, pink, fulvous (bronzed), and rosy-fulvous colors, now they come in an assortment of many more color shades and tints thanks to intensive hybridization. They can now be found in nearly every color except pure blue and pure white. Those with yellow, pink, and other pastel flowers may require full sun to bring out all of their colors; darker varieties, including many of those with red and purple flowers are not colorfast in bright sun.

Awards

The highest award a cultivar can receive in the United States is the Stout Silver Medal, given in memory of Dr. Arlow Burdette Stout, who is considered to be the father of modern daylily breeding in North America. This annual award—as voted by American Hemerocallis Society Garden judges—can be given only to a cultivar that has first received the Award of Merit not less than two years previously. The 2014 winner of the Stout Silver Medal is 'Webster's Pink Wonder', hybridized by Richard Webster and introduced by R. Cobb.
