Ericameria nauseosa (formerly Chrysothamnus nauseosus), commonly known as Chamisa, rubber rabbitbrush, and gray rabbitbrush, is a shrub in the sunflower family (Aster) found in the arid regions of western North America.
Two subspecies have been described, consimilis (the green form with 8 varieties) and nauseosa (the gray form with 14 varieties).
Ericameria nauseosa is a perennial shrub growing to 2 to 8 metres (6+1⁄2 to 26 feet). The leaves, depending on the subspecies, are 2–7.5 centimetres (3⁄4–3 inches) long and narrow to spatula-shaped. Both the flexible (rubbery) stems and the leaves are greenish-gray with a soft felt-like covering.
It blooms from August to October and produces pungent-smelling, golden-yellow flowers. The flower heads are 6–13 millimetres (1⁄4–1⁄2 in) long and made up of 5 small, yellow, tubular disk flowers, and occur in umbrella-shaped terminal clusters. The shrub reproduces from seeds and root sprouts.
