The Arroyo Willow – Salix lasiolepis – is a native shrub or tree in California and in most Western states.
Wetland Habitat
Willo is important in riparian (creek and waterway) environments;
- it provides habitat and food for insects, birds, amphibians and other animals
- in spring, birds use a cottony substance released by the seeds to build nests
The Arroyo Willow likes to keep its feet wet. It spreads by sending out root runners, which create thickets. (It can also propagate from branch cuttings.)
The species is known as a freshwater indicator. As much as the Arroyo Willow likes water, it is also drought tolerant.
Erosion Control
Along with plant and animal habitat, the Arroyo Willow is used as a natural form of erosion control.
Medicinal Uses
Native Californians and herbalists use the bark and leaves to treat headaches, sore throats, and diarrhea.
Tool Making
The Arroyo Willow is used to make baskets, arrows, furniture, and flutes.
Symbolic
The willow grows long, straight shoots in the spring. These shoots are highly flexible and resist breakage. It symbolizes grief – (bending) and recovery – (bouncing back).
