Cane Chollas (Cylindropuntia spinosior, formerly Opuntia spinosior) have lovely brilliant pink to magenta flowers. The other species of chollas found here in Tucson can have pink flowers (perhaps from crossing with Cane Chollas in the past), but they are generally less intensely colored.
Cane Chollas can be found growing throughout the Tucson area, and they bloom here in April and early May. Cane Chollas have distinctive, spineless, bright lemon-yellow, very bumpy fruits. These attractive fruits are edible either raw or cooked.
