Actaea racemosa ( Black Coshosh ) is a perennial herb that is native to cold and temperate regions of eastern North America and is grown primarily for its medicinal roots and rhizomes. Black Cohosh thrives in shady gardens and produces striking white flowers that resemble fairy candles during late summer and early autumn.
Suitable for Cold and Temperate climates.
Black Cohosh and its medicinal roots and rhizomes have been used to by Native Americans to treat snakebites, lung problems and pain from childbirth. Today, it is widely used as a dietary supplement to assist with menopause and a range of other ailments such as mood swings and digestion issues.
Actaea racemosa is also commonly known as Bugbane, Black Bugbane, Black Snakeroot, Rattle-Top and Fairy Candle.

Growth
Actaea racemosa is a perennial, shade plant that grow to a maximum height of around 1.8 metres (6 feet) and spreads no wider than 1.2m (4 feet). Black Cohosh grows deep green, finely divided foliage and then in the warmer months bears tall tapering racemes containing small white flowers. Up close the flowers smell unpleasant which gives the plant its less appealing common name Bugbane.
The basal leaves are up to 1 metre (3 feet) long and broad, forming repeated sets of three leaflets and have a coarsely serrated margin. The fruit is a dry follicle with one carpel which contains several seeds each.
Black Cohosh attracts plenty bees and butterflies into the summer garden and is ideal for gardeners looking for shade-loving flowers. Kept protected from strong winds, the plants are otherwise trouble-free.
