Formerly Cowania mexicana. Moderate to deeply taprooted evergreen shrub less than 12 ft. tall but occasionally reaching 25 ft., with creamy white flowers, blooming April to October. Adapted to well-drained shallow, sandy to rocky textured soils on foothills, slopes, mesas and high plains of forest woodland, mountain brushland and desert shrubland habitats; 3,000 to 8,000 ft. elevation. Colonizer of open disturbed sites, but is mostly killed by wildfire; may weakly sprout afterwards. Occasionally may produce nitrogen-fixing root nodules. Excellent palatability to livestock and wildlife, especially important as browse on winter range.
