Saguaros have been known to live longer than 150 years. Arms are developed to increase the plant's reproductive capacity, as more apices lead to more flowers and fruit. A saguaro without arms is called a spear.
A saguaro is able to absorb and store considerable amounts of rainwater to survive during periods of desert drought.
The spines on a saguaro grow up to a millimeter per day.
Saguaro flowers bloom April through June. They are white and open well after sunset and close in mid-afternoon.
