Desert broom is a vertical, evergreen, densely-branched shrub usually 3 to 6 feet tall, occasionally up to 10 feet tall. Its many fine twigs are green; the tiny, linear leaves are deciduous during dry periods. The plants are dioecious (that is, each individual plant bears only maleor female flowers) and blooms in the fall. The wind - dispersed, white-tasseled seeds are produced by the female plants in such abundance that the plants and nearby ground appear to be snow-covered.

Desert broom grows in the desert, desert grasslands, and chaparral from 500 to 5,000 feet elevation in Arizona, California, Sonora, and Baja California.

In the winter the cottony mounds crowning the female plant are composed of countless individual fruits. Each seed is attached to many silken, white hairs called pappus. The pappus, serving as parachutes, carry by the wind, the seeds which drift to the ground, collecting everywhere!

Desert Broom is relatively short-lived. It is rarely browsed by mammals, but its strong shade fosters the growth of other plants. Desert Broom is most prominent in the higher areas of our Arizona stream beds.
