Guide
The species-level account. Cultivar pages build on this and say where they differ.
Oreocereus celsianus is a columnar cactus in the Cactaceae, a family of arid-adapted plants that store water in their tissues and rot readily if kept wet. Give it the brightest, sunniest spot you have and a gritty, fast-draining mineral mix. Water deeply but infrequently, letting the soil dry out completely — wait until the mix is bone dry all the way through before watering again, and water even less in winter.
