Common plant species include creosote bush, blackbrush, greasewood, saltbush, big sagebrush, low sagebrush, and shadscale. The Colorado Desert hosts saguaro cactus, Sonoran creosote bush, and Salton Sea saltbush. The area around the lake is sparsely vegetated with samphire, saltbush and bluebush. It predominately eats saltbush and fruits from cacti, as well as grasses. Other common plants of the Mojave Desert include creosote bush, blackbrush, greasewood and saltbush. Four-wing saltbush ("Atriplex canescens") is heavily used in western Nevada. The plains are interspersed with broken hilly country studded with saltbush. Shrubs include Mormon tea, blackbrush, four-wing saltbush and cliffrose. Vegetation in the area is primarily low saltbush and bluebush scrub. The western Riverina consists largely of featureless saltbush plain. Saline areas feature fourwing saltbush, shadscale, and winter fat.

For reasons unknown, sheep seem to prefer the more fibrous, less nutritious river saltbush. Flora consists mostly of mulga bushland and arid shrubland, particularly Saltbush.
