Hemerocallis flava (syn. Hemerocallis lilioasphodelus), known as the lemon lily or yellow daylily, is one of the oldest daylilies in cultivation, dating back to 1762 (hybridized by Linn). It is a species daylily with a graceful, fountain-like habit and sweetly fragrant, lemon-yellow, trumpet-shaped flowers. It blooms in late spring to early summer, earlier than most modern hybrids. Its fragrance and early bloom make it a unique and valuable garden plant.
