Native plant
Native plants include: Barrel cactus, and Smoke trees ("Psorothamnus spinosus")" in some bajadas. The Cleghorn Lakes offer occasional spring wildflower displays. The Crucifixion Thorn ("Castela emoryi") shrub has been found near the eastern edge of the wilderness boundary. It is native to California, Arizona, and Sonora state in Mexico. It listed by the California Native Plant Society as rare in California, but is more common elsewhere in the lower Sonoran Deserts.
