Narrow-leaf Willow is a large clumping shrub native to western North America that grows along streams and in wet areas. It has slender gray stems that turn brown with maturity, bearing linear gray-green leaves. Individual stems live 10-12 years but are replaced by new growth from underground stems. Small yellow-green flowers bloom March through May. It is easily propagated from seed or cuttings and tolerates a variety of soil and water conditions once established. Narrow-leaf Willow provides habitat for wildlife and its young wood is used for basket making.
