This hardy native vine has been used in American gardens since the 18th century, especially for screening porches and summer houses. Also know as Clammy American Birthwort or Shrubby Pennsylvania Birthwort, in 1761 Philadelphia nurseryman John Bartram sent seed to his patron Peter Collinson in London. British taxonomist Dr. John Sims wrote in The Botanical Magazine, 1801, that "the vine was soon adopted for arbors creating a canopy impenetrable to the rays of the sun, or moderate rain." The flowers provide nectar for the native pipe-vine swallowtail butterflies, and the leaves are an important food source for the caterpillars.

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.
