Black cohosh, or snakeroot, has been grown in American gardens since the late 18th century. Thomas Lamboll sent three kinds of snakeroot to Philadelphia nurseryman and plant explorer William Bartram during the late 1700s, and one is believed to be this species. Thomas Jefferson included “Black snake-root” in a list of native medicinal plants in his only published book, Notes on the State of Virginia (1781). Black cohosh is a long-lived perennial that will slowly increase in size for many years and not require dividing. The lacy foliage forms an attractive mound in the flower border or woodland garden.

Bare root planting tips:
~ If you can't plant immediately, store your plant in a cool location and keep the roots moist or pot in a container with a nursery potting mix from your local garden center.
~ Before planting, let the roots soak for several hours as you prepare the site. You'll want to dig a large enough hole so the root mass can spread out and the plant is at the same soil level as when it was growing in the nursery.
~ Once planted, water it in well and wait a month before fertilizing. Mulching will help to maintain moisture and raise soil temperatures for faster growth.
