  • Comments: A low growing plant, M. Heyderi is among the most cold hardy of the Mammillaria. It is among the easiest of Mammillaria to grow, but one must be patient, as increases in size come slowly. In the winter, expect the plant to shrink, perhaps even down to the level of the soil. It has a large root, so using a deeper pot than normal is appreciated as is strong light exposure.
