About
Actaea simplex is a herbaceous perennial that forms clumps and reaches heights of up to 1.5 meters (5 feet). It features slender, branched racemes adorned with aromatic, white flowers resembling bottlebrushes. After flowering, black berries develop on the stems, which rise above finely dissected, dark green leaves.
About the genus
Actaea consists of herbaceous perennials that grow from rhizomes. They feature compound leaves and produce small, creamy-white flowers arranged in compact, upright racemes that can be simple or branched. These flowers may later develop into toxic berries that can be red, black, or white, or into clusters of star-shaped brown follicles.
