Totem Pole Cactus are named for their multiple tall and cylindrical stalks that have a bumpy surface, sometimes resembling other patterns in nature. The thornless stalks are smooth to the touch and grow in a tight cluster around the base of the original plant. Found in the southern parts of Mexico and areas of South America, Totem Pole Cactus are highly resistant to heat, and resistant to all but the harshest winters, so they're suitable for growing in Arizona. They do require more periodic irrigation then what other cacti require, but the brilliant green stalks the Totem Pole Cactus add to your landscape are well worth it.
