The Sonoran is the only place in the world where the famous saguaro cactus ("Carnegiea gigantea") grows in the wild. Cholla ("Cylindropuntia" spp.), beavertail ("Opuntia basilaris"), hedgehog ("Echinocereus" spp.), fishhook ("Ferocactus wislizeni"), prickly pear ("Opuntia" spp.), nightblooming cereus ("Peniocereus" spp.), and organ pipe ("Stenocereus thurberi") are other taxa of cacti found here. Cactus provides food and homes to many desert mammals and birds, with showy flowers in reds, pinks, yellows, and whites, blooming most commonly from late March through June, depending on the species and seasonal temperatures.
