Pot: 10 cm.
It is a beautiful columnar cactus with a shrubby habit, which in nature reaches up to two meters in height, maintaining an extremely small diameter, less than 10 centimeters! The stems have a bluish-green color, waxy and light-colored due to the whitish pruina that covers the plant to protect it from atmospheric agents. From small and slightly black felted areoles, sparse dark-colored spines emerge. This plant usually blooms in winter and only at night: its flowers last about one day, but they are so big and beautiful with their delicate colors, that they certainly don't go unnoticed!
