Hemerocallis 'On Top'

Daylily

Hemerocallis ‘On Top’ is a vigorous, tall perennial valued for its bright yellow blooms and elevated flower display. Arching, strap-like green leaves form a dense clump in spring, followed by tall scapes bearing abundant, clear yellow flowers in mid-summer, held well above the foliage for strong visual impact, with each bloom lasting a day but produced over several weeks. Its height and color make it an excellent background or focal plant.
