Description

This Sonoran desert native has attractive grey bark. Frost or drought can induce leaf drop. Summer monsoons can trigger regrowth. The stems are armed with vicious thorns. In spring, there are masses of lavender pea like flowers. This tree needs no water in deep soil. The seeds are edible. Leaves are 2" long and 1" wide. Do heavy pruning only in cooler months. It is native < 2500' in sandy washes. Give some frost protection when young.

Water Saving Tip:

Change spray sprinklers to low-flow bubbler or drip systems. Shrubs and trees are ideal candidates for this type of irrigation because the water is applied directly to the root zones.
