The Saguaro cactus can live for 200-300 years in the Sonoran Desert.

The Saguaro cactus (Carnegiea gigantea) is known for its incredible longevity. Under ideal conditions, it can live for 200-300 years, growing very slowly during its early years. It may take up to 10 years to grow just a few inches, but as it matures, it can grow over 40 feet tall. The Saguaro cactus plays a vital role in the desert ecosystem, providing habitat for numerous species, such as birds and small mammals. Its long lifespan allows it to produce seeds that help sustain the desert environment for generations.
