Psorothamnus spinosus

Smoke Tree
Fabaceae (Leguminosae)
Deciduous, Shrubs, Trees

Native to the deserts of Arizona, Southern California, and Baja California. Grows to 10–20 ft. tall and 10–15 ft. wide. Sparsely foliaged in small, hairy white leaves that drop in early spring, revealing an intricate network of silvery gray, spiny branches; the leafless plant is said to resemble a cloud of smoke. In late spring, puts on a good show of fragrant, violet-purple, sweet pea–shaped flowers in 1 1/2–2-in. clusters. Cut branches (in or out of bloom) are good in arrangements. Not always vailable in nurseries but easily started from seed in warm weather. Provide good drainage. Needs little care.
