Saguaro cactus continue growing until they're about 100 years old, reaching a standard height of 20-30 feet, with a few as large as 40-50 feet. The lifespan of this plant is approximately 200 years.
The largest known living saguaro is the Champion Saguaro growing in Maricopa County, Arizona, and is 13.8 m (45.3 ft) tall with a girth of 3.1 m (10 ft). The tallest saguaro ever measured was an armless specimen found near Cave Creek, Arizona; it measured 78 feet tall before it blew over in a windstorm in 1986. Whenever it rains, saguaros soak up the rainwater. The cactus will visibly expand, holding in the water. It conserves the water and slowly consumes it.
