Black Cohosh is a native perennial of moist woodlands with bushy green foliage. It is slow to establish but puts on a tremendous show of flowers once mature. The white flowers have a musky fragrance that is more appealing to its beetle pollinators than most people. Racemes that can be up to 24″ long shoot up between June and August, with each bloom lasting about a month and the inflorescence persisting for weeks thereafter. The fruit is an inconspicuous follicle that splits to disperse small seeds.
In a garden with dappled shade, even moisture and good soil, Black Cohosh can grow into a stunning specimen, or it can naturalize into a suitable site through its fibrous rhizomes and by seed. If allowed to dry out completely or exposed to too much sun, the foliage may go yellow. Deer and other mammals do not bother the foliage (it is in fact toxic) but the flowers provide both nectar and pollen for insects.
Black Cohosh has a long history of medicinal use, most notably for menstrual issues, for which it is prescribed in Europe*. Clinical trials are ongoing and as with any medicinal plant, proper research is necessary before any use.
