COOL FACTS ABOUT THE SAGUARO CACTUS
The Saguaro Cactus is the largest cactus in the United States.
Saguaros can live up to 200 years (although some sources state that they can live even longer than this). They grow at a very slow rate, only an inch per year. A 10 year old plant may only be 2 inches tall.
Many, but not all, of the Saguaros grow arms.
The Saguaro cactus flowers from mid-May through early June. During our visit on June 12, all of the cacti had already finished blooming.
The inside of the cactus is made of wooden ribs which resembles a tree trunk. Growing over these ribs is the green, fleshy skin that absorbs and stores water. The cacti absorb gallons and gallons of water in the summer monsoon season and use this stored water throughout the remainder of the year.
While in Saguaro National Park, please practice the seven principles of Leave No Trace: plan ahead, stay on the trail, pack out what you bring to the hiking trail, properly dispose of waste, leave areas as you found them, minimize campfire impacts, be considerate of other hikers, and do not approach or feed wildlife.
