The saguaro is found only in the Sonoran Desert, which includes about 120,000 square miles of California and Arizona. Most of Baja California and half of the state of Sonora, Mexico is also included. You won't find saguaros above an elevation of about 3,500 feet since they can't handle much frost.

Can a saguaro cactus really be grown from seeds in a pot? Yes, you can purchase seeds from various gift shops around town.

If you care for it properly, it will grow. The issue is, you probably won't be around long enough to watch it get very tall.
