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.
Should be removed within 30′ of structures. Separation of plants from 30′ to 100′ of structures is important. If removal is not an option, maintain completely free of dead twigs and leaves. Can be made slightly more fire resistant with indirect watering once a week.
