[Wikipedia] Ecology: Of all of the endemic California plants, those of the family Asteraceae have the highest affinity for serpentine soils, based on the number of species represented in these serpentine plant communities.[12] Most serpentine endemism is concentrated in the North Coastal and Klamath Mountain Ranges of northwestern California and southwestern Oregon.
