Noteworthy Characteristics

This species of goat's beard is a Missouri native plant which occurs in moist woodlands and along bluffs in the central and southeast part of the State. A tall, erect, bushy, clump-forming plant typically growing 4-6' high which features pinnately compound, dark green foliage and showy, plume-like spikes of tiny, cream colored flowers which rise well above the foliage in early to mid summer, creating a bold effect. This rose family member is somewhat similar in appearance to astilbe. Dioecious (separate male and female plants) as the species name suggests. Plants with male flowers (numerous stamens per flower) produce a showier bloom than plants with female flowers (three pistils per flower).

Problems

No serious disease or insect problems. Some susceptibility to leaf spot.

Garden Uses

Excellent background plant for shady, moist spots in the border or in a woodland, wild or native plant garden. Plant as a specimen or in groups along streams or water gardens.
