It is primarily cultivated in Asia and Latin America. It is a perennial plant that grows very quickly.

Its highly original stems (often referred to as leaves) typically measure 10 to 15 centimeters in length and feature 3 to 4 ribs.

It is a cactus with few spines and is therefore not dangerous to handle.
