What is cactus column?

As an AI language model, I can suggest some information about cactus column:

A cactus column is a type of cactus that is cylindrical in shape and has vertical ribs on the surface. It is also known as a "pillar cactus" or "columnar cactus." Examples of cactus columns include the Totem Pole cactus and the Organ Pipe cactus. They are typically found in hot, arid regions such as the Sonoran Desert and the Baja California Peninsula.

Cactus columns can grow to be several feet tall and have many branches emerging from the central column. They are capable of storing large amounts of water in their stems, allowing them to survive long periods of drought.

Cactus columns are popular ornamental plants due to their unique shape and interesting texture. They are relatively easy to care for and can be grown both indoors and outdoors. However, they should be kept in well-draining soil and protected from frost. Some species also produce beautiful flowers in the spring.
