What is Black Cohosh?
A tall growing, unpleasantly scented, woodland perennial plant, 3-8 feet high. The large creeping, knotty rootstock, scarred with the remains of old growth, produces a stem of up to 9 feet in height. Large compound leaves thrice-divided, sharply toothed, terminal leaflet 3-lobed, middle lobe is the largest. Small, fetid, flowers are white and strong smelling, in very long, slender, fluffy, spikes, terminating tall leafy stalks, each flower has numerous white stamens and no petals, May to September. Tufts of stamens conspicuous. Flowers ultimately give way to small, round seed pods with several seeds. When the stalk is shaken, the seeds rattle within their pods, producing a sound similar to a rattlesnake, thus the nickname "rattleroot". Grown in shade or full sun, but is grown more vigorously in the sun. Zones 3-10. Not heat-tolerant. Wiry stems with divided dark green leaves and wandlike racemes of white flowers is very showy.
