Saguaro
Carnegiea gigantea
The 'King' of cactus, Saguaros first blossom when they are 40 to 50 years old (6 to 8 feet tall) and do not begin to develop arms until 75 years. The night blooming flowers are pollinated by bats and other nocturnal creatures and last only through the next day. Saguaro fruits have long been consumed by Native Americans and wildlife. Because the Saguaro is the largest growing cactus in North America its root system prefers rocky soil to help support the massive weight of the plant. As with all native plants, the Saguaro Cactus is protected by the United States government and permits are required before removal. Can be damaged by heavy frost, to protect in cold weather cover the tips of the saguaro, this where most of the water is stored. Canopy Value for this plant is 3 for a spear or 28 with arms.
