  • Foliage – The leaves are opposite, compound (with 3-5 leaflets), and the margins are entire.
  • Leaflets are each 2-3 in. (5-7.6 cm) long.
  • FlowersWhite, fragrant, four-petaled flowers appear in the late summer through the fall.
  • Fruit Seeds are also showy and production is prolific. Seed heads have long, silvery-gray, feather-like hairs attached.
  • Ecological Threat – The native species (C. virginiana) is very similar (margins of leaves of the native tend to be toothed), but not as prone to self-seeding and spreading. Clematis terniflora prefers sun to partial shade and is found invading forest edges, rights of ways and urban green space especially near creeks.
  • It is native to Japan and China and was introduced into the United States as an ornamental plant.
