Organpipe cactus, Organ-pipe cactus
Synonym(s): Cereus thurberi, Lemaireocereus thurberi, Pachycereus thurberi
USDA Symbol: STTH3
USDA Native Status: L48 (N)
This tree-like cactus, 9-20 ft. tall, bears many branches from its short-trunked base. Lavender flowers bloom nocturnally. The red, fleshy fruit is edible.
This cactus branches at the base, which gives the stems the appearance of organ pipes. Since these sentinels of the desert are very sensitive to severe winter frosts, they are found only in the warmest parts of the Sonoran Desert. They do occur in extreme southern Arizona, where they are celebrated at Organ Pipe Cactus National Monument. In Mexico, the large, delicious fruits are made into a candy called pitahaya dulce. The nocturnal flowers are beautiful and often attract bats.
