Of conservation concern. Eriogonum arizonicum is widely distributed in scattered and isolated populations across central Arizona from extreme eastern Mohave and southern Yavapai counties through northern Maricopa County to southern Gila and northern Pinal counties. It rarely is common in any location. Limited field observations suggest that some individuals in a population may be first-year flowering perennials.
