Also known as the purple prickly pear, this incredibly beautiful Mexican Opuntia cactus develops fantastic purple pads that perfectly compliment the bright yellow (sometimes red) flowers. Native to Northern Mexico from Baja California to the Chihuahuan Desert, its American range extends only into Pima County in Southern Arizona where these were found in peak bloom and photographed just outside of the park borders of the Organ Pipe Cactus National Monument.
