Black Cohosh | Plant Profile

Black Cohosh (Cimicifuga ramosa) are perennials with tall, upright stems that support clusters of white, fluffy flowers. The dark green foliage is dense and clump forming.

Black Cohosh prefers fertile, medium moisture soils in part shade to full shade. The soils should remain consistently moist. If the soil dries out, leaf scorch and wilting is possible. A layer of mulch can help to maintain consistent soil moisture. Black Cohosh can be slow to establish and should be guarded from strong winds.

Black Cohosh can bring height to woodland or naturalized areas. The tall flower stalks can be quite ornamental when the plants are grouped and in full bloom.
