Blue Cohosh is another beautiful plant that is commonly found in hardwood forests in southern Appalachia. The plant grows to about 3 feet in height and early in the year can have very blue foliage. In spring it puts on yellowish-green flowers which develop into a cluster of blue-purple berries. The rhizomes can be divided in spring or fall and the plant will spread naturally. Seeds are difficult and slow to germinate and should be kept moist. Blue cohosh is another woman's herb, the root of which was traditionally used as a childbirth aid. It is easy to grow but the market is small.
