Guide

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

Cereus jamacaru is a columnar succulent tree from the semi-arid regions of Brazil, built to store water and endure long dry spells. Give it the brightest spot you have, ideally direct sun, and gritty fast-draining mix, then water deeply but rarely — only once the soil has dried out completely through the pot. It rots far more easily than it goes thirsty, so when in doubt, wait.
