Description New Mexico locust is found across the southwest and is common in canyons and openings in woodlands all over Arizona. This tree is especially common after fires where it fills in recently opened ground, and then becomes an understory plant as larger trees fill in. When in bloom this species breaks out in a display of showy pink flowers followed by gland covered beans. It is worth noting that N.M. locust has vicious curved thorns in pairs, so it is wise to plant it away from walkways or places where spines could be an issue.
