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 and endure long dry spells. Give it the brightest spot you have, ideally several hours of direct sun, and a gritty, fast-draining mix. Water deeply only when the soil has been completely dry for several days, then let it dry out fully again before the next watering.
