About

Opuntia engelmannii is a prickly pear common across the south-central and Southwestern United States and northern Mexico. It goes by a variety of common names, including desert prickly pear, discus prickly pear, Engelmann's prickly pear in the US, and nopal, abrojo, joconostle, and vela de coyote in Mexico.

The nomenclatural history of this species is somewhat complicated due to the varieties, as well as its habit of hybridizing with Opuntia phaeacantha. It differs from O. phaeacantha by being green year round instead of turning reddish purple during winter or dry seasons, as well as having yellow flowers with red centers.

Where it grows

O. engelmannii is native to sub-tropical regions of North America. It prefers hot, dry conditions, but is more frost-tolerant than other species of Opuntia. O. engelmannii range extends from California to Louisiana in the United States, and from Sonora (state) and Chihuahua (state), to the Tamaulipan matorral in north and central Tamaulipas.

Uses

The fruits were a reliable summer food for Native American tribes. The Tohono O'odham of the Sonoran Desert in particular classified the fruits by color, time of ripening, and how well they kept in storage.
