Chrysothamnus, known as rabbitbrush, rabbitbush, and chamisa, are shrubs in the sunflower family.[2][3][4] 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.[1]

Chrysothamnus may grow up to a 120 cm (47 in) tall shrub or subshrub, usually with woody stem bases.[1] 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 (though sometimes upwards of 40) yellow disc florets and no ray florets.[1]

Chrysothamnus species are used as food plants by the larvae of some Lepidoptera species including Coleophora linosyridella, Coleophora viscidiflorella (which have both been recorded on C. viscidiflorus) and Schinia walsinghami.[citation needed]
