Saguaro
Carnegiea gigantea
The saguaro is a tall tree height cactus found throughout southern Arizona and northwestern Mexico. The saguaro can grow to 70′ tall but on average, a mature saguaro will reach 30′.
Saguaros flower in April through June and produce ruby colored fruits. Saguaros eventually grow arms (those without arms are called spears) and can be as old as 150 years old!
