Orange Day Lily

Introduced from Asia. Blooming period is about a month during midsummer, and each bloom lasts only a day. “Has been in cultivation for a long time and often outlasts the buildings that surround it and their inhabitants.” Lily Family. Thanks to Alert Flowerophile and Day Lily Queen Donna for pointing this out and assuring me it counts as wild.
