The Sonoran Desert is home to the Saguaro cactus.

The Saguaro cactus is a symbol of the Sonoran Desert, which spans parts of Arizona, California, and Mexico. Known for its tall, tree-like appearance and iconic arm-like branches, the saguaro is the largest cactus species in the U.S. and can live for over 150 years. The saguaro is crucial to the desert ecosystem, providing shelter and food for various animals. It blooms with large white flowers in the spring, which are pollinated by birds, bats, and insects. The Sonoran Desert's unique climate and terrain support this cactus, making it an iconic plant of the region.
