Discussion | Although widely cultivated because it is the only species of Clematis with truly red flowers, C.texensis is native only to the southeastern part of the Edwards Plateau, Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Reports of Clematis glaucophylla from other southeastern states have been based on misidentified specimens (W. M. Dennis 1976). Recent reports of the species in Arkansas, Kentucky, Louisiana, and Virginia have not been confirmed. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
