- Description
-
In the buttercup family, Actaea spp. are perennial herbs grown from a thick rhizome that emerges in the spring. They will produce one or more branching stems. Depending on the variety, each stem will have either three leaves that branch towards the top or three compound leaves and one flower stalk from the central stem. Their leaves are spreading, pinnately divided with toothed leaflets. The flowers are small and white in a terminal, erect raceme. The fruit is white, red, or purplish-black berries with a black dot and often on thick, red stalks. The black dot's on the berries lead to the common name, Doll's Eyes.
It can be grown in an area with partial to full shade but will produce more flowers when placed in sunlight. When grown in deep shade, the stalks will bend toward bright light.
The poison does not affect birds, they will eat the fruit. Small mammals will not eat the pulp but will consume the seeds.
It is typically found in forests or natural areas, as well as rich woods.
Insects, Diseases and Other Plant Problems: All parts of this plant are poisonous, with the berries and roots being the most hazardous.
