Tepary bean
Phaseolus acutifolius, also known as the tepary bean, is a legume native to the southwestern United States and Mexico that has been grown there by the native peoples since pre-Columbian times. It is more drought-resistant than the common bean and is grown in desert and semi-desert conditions from Arizona through Mexico to Costa Rica. The water requirements are low. The crop will grow in areas where annual rainfall is less than 400 mm (16 in).
