Cold Hardy Cacti
The Prickly Pear comes in numerous species. The one from the Mojave Desert is an excellent example of a cold hardy cactus.
Again check with local authorities on this species. This cactus may need a bit more protection than planting in the open depending on where you live. Always check for fungus when this cactus comes out of dormancy and use a common shrub fungicide. Remove any winter rot or diseased areas if necessary. Generally though it will tough out most winters in the dry areas of the Western United States.
cholla. Cholla cacti are found in all the deserts of the West. This cholla was rescued from a fire. It may be a Walking Stick variety, but I could be wrong. Cholla from the western plains, Mojave Desert and lower Great Basin should survive unprotected. When in a garden though they need to be cut back frequently as pads grow fast and if not groomed properly as a shrub, they can grow out of control.
