How long does day lily flower last?
The daylilies comprise the small genus Hemerocallis of flowering plants in the family Hemerocallidaceae. Despite the name they are not true lilies (Lilium, Liliaceae). The name Hemerocallis is based on the Greek words for day and beauty, which reflects the fact that the individual flowers last for only one day. The flowers of most species open at sunrise and wither at sunset, to be replaced by another one (sometimes two or none) on the same stem the next day; some species are night-blooming. Because individual flowers are short-lived, they do not make good cut flowers for formal flower arranging although they otherwise make good cut flowers as new flowers will continue to open on cut stems over several days.
