Discussion | Clematis terniflora is commonly cultivated as an ornamental. It is widely naturalized in the eastern United States. The name C. paniculata J. F. Gmelin was incorrectly used for this species by Thunberg in 1794. Some authors have recognized two or more varieties in this species, correlated with their distribution in Asia, but in the study by H.Hara (1975), all of the varietal names were reduced to synonymy.

Clematis lasiantha is common in the Coast Ranges and the foothills of the Sierra Nevada of California. The Shasta used pounded stems or chewed or burned roots of Clematis lasiantha medicinally in the treatment of colds (D. E. Moerman 1986).
