Adenostoma fasciculatum is a flowering plant native to Oregon, Nevada, California, and northern Baja California. This shrub is one of the most widespread plants of the chaparral biome. This plant is a major component of the chaparral and is holding the soil on the hillsides in California. Chamise also protects the soil after fires as it crown sprouts back from the base. A good understory plant that grows well under chamise, with a nice mulch of chamise leaves and twigs, is Viola pedunculata.
