Opuntia polyacantha

Opuntia polyacantha is likely the most widespread Opuntia species in USA. These frost and drought tolerant plants range from California to Texas and way north.
This pink-flowered form grows in Beaver Dam mountains, on Utah-Nevada-Arizona border. This area sees snow over winter and not much summer rains. The flowering period for this cactus is spring, when plants plum with water supply from winter snow and rains.
