Discussion

Clematis virginiana is the most frequent and widespread virgin's-bower in eastern North America. It is easily distinguished from C. catesbyana by the presence of three ovate leaflets.

Native Americans used infusions prepared from the roots of Clematis virginiana medicinally to treat kidney ailments, and mixed them with milkweed to heal backaches and venereal sores. Decoctions of stems were ingested to induce strange dreams. In addition, the plant was used as an ingredient in green corn medicine (D. E. Moerman 1986).
