Zizyphus obtusifolia-Gray thorn 

Gray Thorn
is a durable landscape shrub that will reach a mature size of about 6' tall by 8' wide. Branches are waxy and gray-green, most end in a terminal thorn. Flowers are insignificant, but blue-black berries in summer provide some interest, as well as a wildlife attractant. Gray Thorn is native across a wide range in the Southwest, from California east to Oklahoma and Texas, and south into Mexico. Zone 8.
