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.
