Goatsbeard (Aruncus dioicus)
ah-RUN-kus dy-oh-EYE-kus
Synonyms:  A. sylvester
Genus:  Aruncus
Goat's beard is a perennial native to eastern North America and parts of Europe and Siberia. It is grown for its tall stature (up to 6 feet) and showy, cream-colored plumes of flowers in summer. The effect is that of a giant astilbe. Plants with male flowers produce showier and more erect plumes than plants with female flowers, whose plumes are more pendent and less creamy-white. Grow in a woodland garden or moist border, or at waterside.
Noteworthy Characteristics:  Tall, native perennial with showy plumes of creamy-white or greenish-white flowers in summer.
Care:  Grow in moist, fertile soil in full or partial shade. This species can also tolerate drier conditions in full sun. Deadhead to control unwanted seedlings.
Propagation:  Divide in early spring or fall. Sow seed in a cold frame in autumn or spring. Self-sows freely.
Problems:  Generally easy to grow, but fly larvae and tarnished plant bugs may be problems.
