Black Cohosh is an attractive perennial herb native to the Midwestern and Eastern United States. The leaves are large with three pinnately compound divisions and irregularly toothed leaflets. Tall plumes of cream to white flowers, on a wand-like raceme, bloom from May to July, often-towering over six feet. From August to October, seeds develop in capsules and make a rattiling sound when they are mature and ready to be harvested. It prefers rich, moist, soil that is high in organic matter. In its natural habitat, it is usually found in shaded or partially shaded areas, although it will grow in full sun. Black Cohosh can be grown successfully in raised beds in the woods and in raised beds under an artificial shade structure, it is important to choose a site with well-drained but moist soil. Raised beds are highly recommended, especially for clay soils or areas that tend to stay wet after a heavy rain.
