Joan Senior Daylily is a reblooming evergreen perennial with strap-like deep green foliage that is notable for its large blooms. The fragrant near white flowers have a yellow watermark and green eye with lightly ruffled edges. The continuous blooms begin in summer and last for two months, with each flower lasting a day attracting butterflies and pollinators. Grows best in deep rich well-drained soils. Drought, salt, and pollution tolerant once established.
