There are about 15 species and with over 50,000 cultivars of evergreen, semi evergreen, and herbaceous perennials, in this genus. They occur Daylilies are found at forest margins, in mountainous areas, marshy river valleys, and meadowland in China, Korea and Japan. They are mostly clump forming, and occasionally rhizomatous, with arching, strap shaped, dark green leaves, usually 30-48″’ long, but often only 9-14″ long in dwarf or compact species and cultivars. Flowers are often fragrant, held on erect stems, mainly from late spring to late summer. Many daylilies are remontant, flowering repeatedly during the season. The flowers range in color from almost white through yellow and orange to dark purple and deepest red-black. Most flowers last for only one day, in nocturnal daylilies, the flowers open in late afternoon, and last throughout the night. The flowers of extended-blooming daylilies remain open for at least 16 hours. The flower size varies from 3″ miniatures to giants” or more, single or double and plant height ranges from 24″ to 36″ tall.
