Guide

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

Mammillaria haageana is a small clustering cactus from arid regions of central and southern Mexico, built to store water and endure long dry spells. Give it gritty, fast-draining mineral soil and the brightest spot you have, ideally direct sun. Water deeply only when the mix has gone completely dry to the bottom of the pot, then let it dry out fully again before the next watering; when in doubt, wait longer, as this plant rots far more easily than it droughts.
