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.
