It is native to the southwestern United States where it grows in desert scrub habitat. It is a low, neatly mounded plant producing spreading stems which are hairless to densely woolly in texture. Leaves are borne on long petioles. The leaf blade is variable in shape, generally roughly rounded, and up to 2 centimeters long. It has a wavy, bluntly toothed edge and a bumpy, velvety surface coated in woolly fibers and shiny hairs. It is brownish to gray-green to very pale green in color.
