Chaparral Clematis
Clematis lasiantha

About Chaparral Clematis (Clematis lasiantha) Chaparral Clematis is a creamy-white flowering vine, belonging to the Ranunculaceae family, of the large Clematis genus. It is found on the Pacific coast of North America, from the San Francisco Bay Area southwards into Baja California. It extends as far east as the western foothills of the Sierra Nevada mountains, at elevations below 1,800 meters. It grows on hillsides, in chaparral, and in open woodland. Its leaves are 3-lobed, and generally grow groups of three to five leaflets, the largest leaves on the plant normally being between 3 and 5 centimeter in size. It can be distinguished from the similar (but much more widely ranging) Virgin's Bower (Clematis ligusticifolia) by the fact that lasiantha normally only has one flower on each stalk, and at most three, whereas ligusticifolia has multiple flowers on each stem. Virgin's Bower is more likely to be found along streams or in other wet places, whereas the lasiantha tolerates more open, drier places.

Chaparral Clemitis is easy to grow, and grows fast up to 15 feet if there are trees or bushes that it can wind through. It prefers part shade, but will tolerate full shade though grow more slowly. Best to plant in shaded, rocky, well draining slopes. It tolerates summer water up to 1x per month, but shouldn't need it if properly sited. In the drier parts of its range, it does best on north facing slopes.
