Information on the Barrel Cactus

Identification

• Barrel cactuses, also known as ferocactus, are cylindrical cactuses that are about 5 to 6 inches in diameter, according to Clemson University. They are covered with long, sharp spines and can grow up to a foot tall.

Types

• There are a few varieties of barrel cactuses available. The compass barrel cactus has deep red spines while the candy barrel cactus has distinct red and white spines. All varieties of barrel cactuses bloom with flowers that can be purple or orange.

Care

• Like all arid cactuses, barrel cactuses can tolerate a good deal of neglect as long as they are kept in well-drained soil. Be sure that your cactus is not kept in standing water as it will quickly rot the roots.
