Day lily (Hemerocallis)
Day Lily Facts
The genus Hemerocallis is native to the countries in the temperate parts of AsiaJapan, Siberia, Korea, China, and Eurasia.
Since the early 1930s, hybridizers in the United States and England have made great improvements in daylilies. Originally, the only colors were yellow, orange, and fulvous red. Today, we have colors ranging from near-whites, pastels, yellows, oranges, pinks, vivid reds, crimson, purple, nearly true-blue, and fabulous blends.
Many people are familiar with only the common yellow or orange daylilies which are often seen along roadsides. These daylilies are cultivated forms of the wild types of daylilies which have “escaped” and are growing as if they are wild. All the modern daylilies have been developed through a complicated history of hybridization among these and other wild types.
The daylily can be characterized as a clump-forming, herbaceous perennial with fibrous or somewhat tuberous roots. More facts here
