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).

Of conservation concern. Clematis socialis, the only species of Clematis subg. Viorna in the flora with horizontal, patch-forming rhizomes, is known only from three small populations in St. Clair and Cherokee counties south of Ashville, in northeastern Alabama.
