Saguaro



          Carnegiea gigantea         Cactaceae


















          D ESCRIPTI O N
          Saguaro is an arborescent-stemmed cactus.
          Stems are simple and have one to several lateral
          curving, erect branches. Trunks have prominent
          ribs with rows of clumped, stout spines. Flowers
          are white and showy, and appear on the branch
          tips in spring. Saguaro fruits are red to purple,
          ellipsoid, oblong, and contain as many as 2,500
          seeds. Saguaro cacti are a valuable resource for
          desert wildlife; birds depend on saguaros for
          water and nutrition in the driest, hottest times of
          year, just before the summer monsoons.

          •   Saguaro occurs throughout most of the
              Sonoran Desert in southern Arizona and
              northwestern Mexico.
          •   Saguaro fruits were a major food staple of
              Southwestern tribes, and they have a unique
              cultural role in the Tohono O’odham tribe.
              Tohono O’odham peoples harvest and
              process saguaro fruits for food and wine in
              preparation for the annual rain ceremony.
              Saguaro ribs are used as building material for
              fences, ramadas, homes, and in ceremonial
              roundhouses. Symbols indicating important
              events are carved on saguaro ribs as “calendar
              sticks.”
