Goat's Beard has large white Astilbe-like flowers in June, held well above the plant. It prefers moist, shady locations and it is particularly gorgeous planted in masses. The flowers attract numerous butterflies, pollinators and bees. Aruncus dioicus is dioecious (separate male and female plants). Both flower but the male plants are more floriferous having numerous stamens per flower while the female flower has only 3 stamens. The genus name Aruncus comes from the Greek word for goat’s beard. Best if pruned back after flowering to promote bushy growth.
