Black cohosh (Actaea racemosa) ak-TAY-ah rass-ih-MOE-sah Synonyms:  Cimicifuga racemosa Genus:  Actaea

Actaea racemosa is a native woodland perennial with white, somewhat fuzzy flowers in midsummer that wave above astilbe-like, deeply cut foliage. The flowers can be unpleasantly scented, thus the name "bugbane." Formerly in the genus Cimicifuga, this plant is great for use in a woodland garden or moist border.

Noteworthy Characteristics: 

Two-foot-tall racemes of white, bottlebrush flowers. Native to eastern North America.

Care: 

Moist, fertile, organically rich soil in partial shade. Provide support if necessary.

Propagation: 

Divide in spring, or sow seed as soon as ripe in a cold frame. Seeds will germinate the following spring.

Problems: 

Relatively trouble-free, but can be affected by rust, tarnished plant bug, and other leaf-feeding insects.
