Desert Hackberry, Granjeno
Deciduous, Edible fruit, Shrubs, Trees
Related to elms (Ulmus) and similar to them in most details, but smaller. All have virtue of deep rooting; old trees in narrow planting strips expand in trunk diameter to nearly fill strips without producing surface roots or heaving sidewalk or curb. Good choice for street or lawn tree, even near buildings or paving. Canopy casts moderate shade in spring and summer; leaves turn yellow in fall. Mature trees have picturesque bark with corky warts and ridges. Small berrylike fruits attract birds.
Hackberry is exceptionally tough, tolerating strong winds (stake young trees until well established), desert heat, and dry, alkaline soils. Leaf gall caused by psyllids may disfigure hackberry leaves in some regions (especially in the Rocky Mountain states and Pacific Northwest), but the trees are not harmed. Little pruning required. Bare-root plants, especially in larger sizes, sometimes fail to leaf out.
Native to southwestern U.S. and northern Mexico. Small tree or shrub with dense, spiny growth to 18 ft. tall; variable in width, sometimes growing wider than tall. Small orange berries. Useful in desert areas as a honey source or bird food, for screen or barrier planting, for erosion control.
