Formerly Clematis viorna was locally naturalized near Guelph, Ontario; no recent reports are known. D.S. Correll and M.C. Johnston (1970) mention "a report of a specimen" from Texas; neither the specimen nor further details have been located.
The Fox Indians prepared a drink from the roots of Clematis viorna to use medicinally as a panacea (D. E. Moerman 1986).
