Chrysothamnus Nauseosus

Chrysothamnus nauseosus, also known as rubber rabbitbrush, gray rabbitbrush, or Chamisa, is a shrub of the genus Chrysothamnus that grows in the arid regions of western North America. The large number of identified Subspecies , is the result of significant variation within the species.

It is a shrubby, 12- to 90-inch perennial, producing pungent-smelling, golden-yellow flowers in late summer and early fall. Flower heads are numerous and occur in umbrella-shaped terminal clusters. The shrub reproduces from seeds and root sprouts. Leaves, depending on the Subspecies, are long and narrow to spatula-shaped. Both the flexible stems and the leaves are greenish-gray with a soft felt-like covering.

Along with associated species, like big sage and western wheat grass, rubber rabbitbrush is a significant source of food for browsing wildlife on winter ranges. Dense stands of this species often grow on poorly managed rangelands, in disturbed areas along roadways and on abandoned agricultural property.
