Clematis lasianta blooms from late Winter into early Spring. The Chaparral Clematis can be found throughout the state below 6500 feet. Chapparal Clematis grows up to 20' or more up into trees. You can often see the creamy white flowers of the Chaparral Clematis draped over shrubs or trailing out of the trees in the through the Spring. I like the white poppy-like flowers as well as the feather duster seeds. Clematis lasiantha was use medicinally. The roots are generally found growing in the shade, the top of Clematis lasiantha is generally in the sun. Clematis lasiantha can be found growing in moist or dry soils.
