Clematis lasiantha (Pipestem clematis)
Pisapia, Robert J.

Clematis lasiantha

Clematis lasiantha Nutt.

Pipestem clematis, Pipestems, Chaparral clematis

Ranunculaceae (Buttercup Family)

Synonym(s):

USDA Symbol: CLLA3

USDA Native Status: L48 (N)

A strong, woody climber to 20 ft. or more. Bears few-flowered clusters of creamy-white blossoms on the upper portions of the plant. These are followed by light-catching, silky seed plumes. Deciduous leaves are pinnately compound with 3 leaflets.

Clematis lasiantha, with its cheery white-and-yellow spring flowers and decorative, silky seed plumes in summer, is a member of the buttercup family (family Ranunculaceae). A widely adaptable, tough, and disease-resistant plant, it is a good choice for native plant gardens within its range, which is from north-central California south into Baja California. It can climb to 20 feet and can take light shade or full sun. It is deciduous and may die back completely in cold winters, but will reemerge in the spring. It does well in normal garden conditions. It is less widespread, more delicate, and less vigorous than the related Clematis ligusticifolia.
