Where did daylilies come from?

The day lily is native to Asia and grew wild. But from the early 1930s, horticulturists in the US and in England have come up with a wide variety of daylilies. At first, daylilies were found in only yellow, orange, and a reddish brown. Now, we find daylilies in near-whites, pastels, yellows, oranges, pinks, vivid reds, crimson, purple, nearly true-blue, and other colors. The most common are yellow or orange daylilies and are often seen along roadsides. Today, daylilies of all colors are found in many gardens.
