Iconic Saguaro Cactus
May 14 2018 at 6:12pm EDT
         The saguaro (/səˈwɑːroʊ/, Spanish pronunciation: [saˈɣwaɾo]) is an arborescent (tree-like) cactus species in the monotypic genus Carnegiea, which can grow to be over 40 feet (12 m) tall. It is native to the Sonoran Desert in Arizona, the Mexican State of Sonora, and the Whipple Mountains and Imperial County areas of California. The saguaro blossom is the state wildflower of Arizona. In 1994, Saguaro National Park, near Tucson, Arizona, was designated to help protect this species and its habitat.

         The image of the saguaro is indelibly linked with that of the American Southwest, especially in western films. The common name saguaro came into the English language through the Spanish language, originating in the Mayo language.

         Saguaros have a relatively long lifespan, often exceeding 150 years. They may grow their first side arm any time from 75–100 years of age, but some never grow any arms. A saguaro without arms is called a spear. Arms are developed to increase the plant's reproductive capacity, as more apices lead to 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. Saguaros grow slowly from seed, never from cuttings, and grow to be over 40 feet (12.2 metres) in height. The largest known living saguaro is the Champion Saguaro growing in Maricopa County, Arizona, measuring 45.3 feet (13.8 metres) high with a girth of 10 feet (3.1 metres). The tallest saguaro ever measured was an armless specimen found near Cave Creek, Arizona. It was 78 feet (23.8 metres) in height before it was toppled in 1986 by a windstorm.
