Hemerocallis 'Joan Senior'

Joan Senior Daylily

Hemerocallis ‘Joan Senior’ is a classic, award-winning perennial valued for its large, fragrant white blooms and elegant form. Arching, strap-like green leaves form a dense clump in spring, followed by abundant, ruffled, creamy white flowers with a soft yellow throat in mid-summer, with each bloom lasting a day but produced over several weeks. Its clean color and fragrance make it a standout in borders and moon gardens.
