in the Sonoran Desert
The Organ Pipe Cactus is one of the giant cacti, second in size only to the more iconic Saguaro. Instead of having a single trunk with branches, the organ pipe has 6 to 20 stems all growing from a central trunk. It will typically grow about 15 feet tall, though specimens have measured more than 20 feet in height.
Its habitat is limited to Sonora and Baja California, Mexico, and southwestern Arizona. In the United States, the largest number are found in Organ Pipe Cactus National Monument located near the Mexico/Arizona border.
