Perhaps no desert epitomizes the old Wild West as much as the Sonora Desert - of the most iconic cactuses of the American deserts. The Organ Pipe Cactus National Monument is located in extreme southern Arizona on the border with Mexico. It is the only place in the United States where one can see the Senita and organ pipe cactus growing in the wild.

Not only will visitors see the Senita and organ pipe cactus, but also other types of cacti. Perhaps the most famous park in Arizona is Saguaro National Park - it is home to the giant Saguaro Cactus, the largest cactus in the United States. The Saguaro National Park and the Organ Pipe Cactus National Monument are both in the Sonoran Desert.

The Organ Pipe Cactus

The organ pipe cactus is known as "pitaya dulce" in Spanish (meaning "sweet pitaya" or sweet cactus fruit). Its tennis ball-sized fruit is said to taste better than watermelon and is made up of red flesh. It mostly grows to heights of 5 meters or 16 feet but has been known to reach as much as 7 to 8 meters or 23 to 26 feet.

  • Scientific Name: Stenocereus thurberi

It is found mostly in Mexico - particularly in Sonora, southern Baja California, and Northern Sinaloa. It mostly grows on rocky hillsides up to 900 meters or 3,000 feet in elevation.

  • Grows: Organ Pipe Cactus Monument & Mexico

The cactus doesn't do well in frosts and so is rare in low desert areas that get cold at night. It is slow-growing and likes full sun and well-drained soil. It is normally pollinated by bats.

Next time traveling to Arizona, take time to explore the ecosystem of the Sonoran Desert and its rich collection of cacti. Deserts are often far from desolate and destitute.
