This is a Ferocactus emoryi. Ferocactus emoryi is quite common in Sonora, Mexico, but has the most limited range of the three large barrel cacti in the US, found only in a small area of far south Arizona, centered on Organ Pipe Cactus National Monument, extending northwards only to the vicinity of Ajo. It is also known as Emory's barrel cactus, Coville's barrel cactus and traveler's friend.
This cactus makes a good landscape plant. It is winter hardy to 30 degrees F.

When you re-pot this plant, do not use a pot much larger than 4" diameter. If you put a succulent in a pot that is too large, the soil will take too long to dry since there are not enough roots to absorb the water and your plant may get root rot.
What is the difference between an cactus and a succulent? All cacti are succulents, but not all succulents are cacti. Succulents are plants that store water in their stem, leaves or root system. A true cactus has a structure called an areole. It looks like a patch of cotton from which spines, flowers, branches and roots grow. While some succulents may have spines, they will not have areoles.
