Alluaudia montagnacii is a rare, spiny, columnar tree from the dry spiny forests of southwestern Madagascar, and it is rarely grown outside specialist collections. The key to growing it is to mimic its arid habitat with full sun, sharp drainage and very little water, letting it rest during its dry season.
