Guide

The species-level account. Cultivar pages build on this and say where they differ.

A columnar cactus in the family Cactaceae, built to store water in its thick stem and to endure long dry spells. Give it the brightest, most direct light you have and a gritty, fast-draining mix. Water deeply only when the mix has been fully dry for several days, letting the interval stretch longer in winter — sitting wet is what kills it.
