Chrysothamnus


Chrysothamnus, known as rabbitbrush, rabbitbush, and chamisa, are shrubs in the sunflower family. The native distribution is in the arid western United States, Canada, and northern Mexico. It is known for its bright white or yellow flowers in late summer.
Chrysothamnus may grow up to a tall shrub or subshrub, usually with woody stem bases. The leaves are alternate, sessile or with short petioles, with entire edges. The flowerheads are singular or in clusters. Each composite flower often has five to 6 yellow disc florets and no ray florets.
Chrysothamnus species are used as food plants by the larvae of some Lepidoptera species including Coleophora linosyridella, Coleophora viscidiflorella and Schinia walsinghami.
