They are cacti with a globose body and an intense green color that form colonies and reach 30 cm (11.8") in height. The tubers are large, quadrangular and have white wool in the armpits. They have 0-4 radial spines and 3-6 central spines. The flowers form a crown on the top of the cactus and can be pink, cream or yellow. They bloom in spring. The fruits are 2.5 cm (0.98") long and red.

They are used in pots, in mini cactus gardens, in greenhouses, in rockeries and in gardens of succulents and cacti.

Mammillaria magnimamma grows in full sun or light shade exposure and in hot, dry climates. In winter it's better for the temperature to be above 3 ºC (37.4 ºF).

The soil can be a mixture of 1/3 of blond peat, 1/3 of coarse siliceous sand and 1/3 of vegetable substrate.

Water moderately in spring and summer waiting for the substrate to dry completely. Starting in the fall, reduce watering and do not water in winter.

Fertilize monthly in spring and summer with mineral fertilizer for cacti and succulents.

They do not need pruning.

The main enemies of these plants are excess humidity and attacks by mites and mealybugs.

They propagate by separating suckers or by seeds sown at the end of winter in a slightly humid sandy substrate.
