Discussion | 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).

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.) |
