One of the more naturally upright growing mesquites. Broad, rounded habit. Finely-cut green to blue-green leaflets. White-thorned branches. Yellow catkin flowers. 4 to 6 inch long curving seed pods. Flowers attract bees. Seeds are a food source for birds. Pods and seeds are edible. Moderate litter. It can be cleaned up or left to feed wildlife and enrich the soil. Extra water speeds up growth. Can blow over in strong winds if it has a poor root structure. Poor root structure usually caused by shallow watering, watering only at the tree's base, or girdling roots. Prune in early spring or late fall for shape and to thin canopy if it becomes too dense. Member of the Legume family.
