Plant Profile

Carnegiea gigantea (Saguaro)

This enormous, branching, tree-like cactus is a favorite landscape plant in the deserts of the Southwest. Giant saguaro is native to the Sonoran Desert, from Arizona southward into Sonora, Mexico. In the wild, it is protected due to shrinking habitat and illegal wild-collection of native plants for garden cultivation.
