Tiny in its composure, you may have passed by the scrubby gem while hiking in Baja, California, the Angeles National Forest, the Coconino National Forest in Yavapai County, Arizona, as well as the southwestern corner of Oregon —where it remains a common inhabitant of woodlands, forests, chaparrals, and within the serpentine soils of other native flora and fauna.
