Where Saguaros Grow
Saguaro cacti, Carnegiea gigantea, only grow in the Sonoran Desert. However, they do not grow in all parts of the Sonoran Desert. This map represents the range of the Sonoran Desert (crosshatch) with an overlay of the range of the saguaro cactus (solid). The range of the saguaro is limited by freezing temperatures in winter.
Saguaros are also limited by elevation. They are generally found growing from sea level to approximately 4,000 feet in elevation. Saguaros growing higher than 4,000 feet are usually found on south facing slopes where freezing temperatures are less likely to occur or are shorter in duration.
Did You Know?
The saguaro cactus only grows naturally in the Sonoran Desert. There are approximately 1.6 million individual saguaro plants growing within Saguaro National Park.
