About the Mammillaria Society
The Mammillaria Society was founded in the UK in 1960 to promote and study this genus. Over the decades, the scope has been extended to and now includes the allied genera Acharagma, Cochemiea, Coryphantha, Escobaria (now Pelecyphora), Kadenicarpus, Neolloydia, Oehmea, Ortegocactus, Rapicactus, Thelocactus andTurbinicarpus. Today, the emphasis is also on the cultivation and conservation of these plants. The Society is one of the RHS’s Affiliated Plant Societies.

About the genus Mammillaria
Mammillarias have long been popular plants with cactus growers due to their interesting spines and showy flowers. There are about 140 species recognised, 37 in the closely related Cochemiea and many more subspecies so there are plenty for the enthusiast to grow. Mammillarias are mostly from Mexico with some species also found in southwest USA, the Caribbean and as far south as Colombia. Several species are endangered or critically endangered in the wild. Mammillaria require cultivation conditions to most other cacti, namely full sun, a well drained medium and a winter rest. They can make good houseplants for a sunny windowsill.
