A wonderful sunset across the Sonoran Desert, Tonto National Forest off the beeline highway near four peaks road. Saguaros have a relatively long life span. They take up to 75 years to develop a side arm. The arms themselves are grown to increase the plant's reproductive capacity (more apices equal more flowers and fruit). The growth rate of saguaros is strongly dependent on precipitation; saguaros in drier western Arizona grow only half as fast as those in and around Tucson, Arizona. Some specimens may live for more than 150 years;[1] the largest known saguaro is the Champion Saguaro. It grows in Maricopa County, Arizona, and is 13.8 meters (45.3 ft) tall with a girth of 3.1 meters (10 ft). These cacti can grow anywhere from 15 to 50 feet. They grow slowly from seed, and not at all from cuttings. Whenever it rains, saguaros soak up the rainwater. The cactus will visibly expand, holding in the rainwater. It conserves the water and slowly consumes it.
