The Chaparral clematis is native to the dry foothills of California and Baja California. It is a deciduous vine that grows throughout the chaparral and oak woodland plant communities where it climbs on top of surrounding plants for sunlight and support. Its stems can reach 12-18 ft. long; large numbers of small white flowers with yellow stamen occur in early spring. Seed heads with long feathery tails mature during the summer and are very attractive when backlit by the sun.

Chaparral clematis is valued as a habitat plant throughout its natural range and when grown in native plantings with oaks, toyon, coffeeberry and sugar bush. In these gardens it can be grown on fences and in background areas to provide diversity and summer accent interest.

Water Needs

Chaparral clematis is well adapted to Inland Empire gardens among other native trees and shrubs with low amounts of supplemental water. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. As shown in the chart below, there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water.

Prune when dormant in winter. This is a lovely, but wild plant that climbs, tendrils, and grows where it wants to. It is best to accept this and plant accordingly. It blooms in spring on the previous year's growth, so too much pruning will remove too many blooms (3).
