Mammillarias are a genus of cactus that are good houseplants for a sunny windowsill. They are relatively slow growing and with time will flower. Several species are available at garden centres and supermarkets but your plant may be incorrectly labelled or not labelled at all!
They are easy to grow, requiring similar conditions to other cacti, ie regular watering in the summer, a free draining potting mixture and a dry winter rest. Most commonly seen in cultivation are Mammillaria bocasana, M. elongata, M. karwinskiana, M. polythele and M. spinosissima


The Mammillaria Society focuses on this genus and other closely related cacti and offers a quarterly journal and annual seed list. Become a member or follow us on Instagram and Facebook.
