The Whitethorn Acacia was aptly named for the large white thorns that protrude in pairs from the leaf nodes. Often used as a low-maintenance barrier or buffer plant, this Arizona native will tend to become a thicket of thorny branches if left alone. With some training and pruning, the Whitethorn Acacia will become a small, multi trunked tree. Little to no supplemental water is necessary once established. Fragrant, yellow flower balls attract butterflies and birds in spring and intermittently through fall. Avoid planting near walkways.
