Native to west Texas, New Mexico, and Arizona, this large evergreen shrub grows at lower elevations along arroyos and in canyons. It may be grown as a shrub or shaped into a small, multi-trunked tree. Bright green, fine-textured foliage contrasts well with smooth grey bark. Inconspicuous flowers are followed by winged fruit. Old leaves are shed in the spring, but the tree never goes completely bare. Grow in full sun or part shade and well-drained soil. Provide moderate to ample irrigation to increase the growth rate.
