This cactus was one of our favorite things about Tucson. They grow EVERYWHERE! It is the largest cactus in Arizona and can be more than 50 feet tall! They don't grow their first "arm" until they are more than 5 feet tall. A giant Saguaro can weigh as much as ten tons! The indians used this cactus to make frames for their homes. I pity the man who had to cut it down. Those barbs are sharp. They live to be 150 to 200 years old. Wow!
