Ericameria nauseosa (Rabbitbrush)
Rubber rabbitbrush is also known as gray rabbitbrush, or chamisa. It is highly variable, with several different subspecies located throughout the western United States. It is typically distinguished by having whitish to green flexible stems, felt-like matted hairs, and narrow, thread-like grayish-green alternate leaves. Flower heads are made up of 5 small, yellow, tubular flowers, and are arranged in dense, rounded or flat-topped clusters at the ends of the branches. Flowers bloom from August to October as other plants are fading, providing vivid color and a pollen source for insects late in the summer.
