ak-TAY-ah Common Name: Baneberry
Actaea is comprised of eight species of woodland perennials with toothed leaves, fluffy flowers, and conspicuous berries. They are from temperate regions of the Northern hemisphere and make useful additions to a woodland garden or shady border. The flowers are generally not showy, but the leaves are often attractive and the colorful berries, sometimes resembling doll's eyes, stand out in the garden. Some species will thrive even in dry, full shade.
Noteworthy characteristics: Berries are highly toxic. Good woodland garden plants.
Care: Prefers cool, moist soil of moderate fertility that has been enriched with leaf mold in partial shade. Water during dry spells.
Propagation: Sow seed in autumn in a cold frame, or divide in early spring.
Problems: Ramularia and Ascochyta leaf spots and leaf smut can affect plants.

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.

'Hillside Black Beauty' differs from other bugbanes because of its deep purple–black foliage. From late spring to late summer, it provides the perfect backdrop for colorful foliage and flowering shade plants (it’s even deer resistant). In fall, fragrant, cream-colored flowers emerge on wandlike, 5- to 6-foot-tall wiry stems.
