About
Robinia neomexicana, the New Mexican, New Mexico, Southwest, desert, pink, or rose locust, is a shrub or small tree in the subfamily Faboideae of the family Fabaceae.
Where it grows
Robinia neomexicana is native to the Southwestern United States (southeastern California and southwestern Utah, Virgin River region, east through Arizona and New Mexico, the Rio Grande valley, to far west Texas) and adjoining northern Mexico; from central New Mexico the range extends north into Colorado, mostly the eastern foothills of the Rocky Mountains. In Arizona, it ranges across the Arizona transition zone, the Mogollon Rim and White Mountains, and into western and southwestern New Mexico.
Uses
In New Mexico, Pueblo Native Americans traditionally ate the flowers uncooked. The pods were also eaten raw and cooked by some Native Americans, such as the Mescalero and Chiricahua Apache.
