[calscape.com] Range, Description, Habitat: Salix lasiandra is a native willow tree that grows in virtually every county of the state in wetland-riparian areas. It is a suckering willow that will extend its roots and spread into any area that has sufficient moisture. It was formerly classified as a subspecies of Salix lucida, and some sources may still refer to it by that name. There are two recognized Varieties: Var. lasiandra is widespread. Var. caudata (Shining Willow) is less common and restricted to the Sierras and northward. Like all willows, this species prefers alluvial soils with plenty of water. (link added by Mary Ann Machi)
