The Mammillaria Society



For the cultivation, conservation and study of the genus Mammillaria and allied genera.



Mammillarias have long been popular plants with cactus growers due to their interesting spines and showy flowers. It is the largest genus in the Cactus family with about 250 species and subspecies so there are plenty for the enthusiast to grow. Mammillarias are 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.

Who are we?

The Mammillaria Society was founded in 1960 to promote and study this genus. Over the decades, the scope has been extended to include the allied genera Coryphantha, Escobaria, Neolloydia, Thelocactus and most recently Turbinicarpus. Today, the emphasis is also on the cultivation and conservation of these plants.

Subscriptions for 2022 (Unchanged from 2021)
You can now join and renew safely and securely, using your credit card, through our association with PayPal, the world's leading on-line payments system. Alternatively you can download and print the 2022 Membership Application Form here.
UK Members using Paypal will be emailed a request for their current and past membership subscriptions to be considered as Gift Aid. The Society is in the process of applying for this. We would very much like all members to agree as it pushes further back the time when we have to consider again any increases in subscriptions. Do note that the only increases this year are to non UK membership, and these only to fully cover international postage costs.
Pricing is shown in British Pounds but you will be billed in your local currency. This means that Mammillaria Society membership is now available throughout the world.
PLEASE NOTE: Your Paypal receipt will have an old email address on it. If you need to follow up anything connected with your transaction, please contact This email address is being protected from spambots. You need JavaScript enabled to view it.

DVD1 contains the first 25 years of Journals from the foundation of the Society, formatted as a single searchable Adobe PDF format document. This means that you can search for any text string you like, and with the use of the Adobe Reader you will find all occurrences in the whole 25 volume set that you are searching in.

DVD2 contains the next 25 years, and our newest addition, DVD3 contains the most recent 10 years. Together they form a complete history of the Society journals up to the end of 2020.

We have established pricing for Members and Non-Members, and the differences in costs between UK, Other EU and Rest of the World destinations reflects the differences in postage and handling costs.

The November Issue of each year has a seed list which is available to members only at that time. Later in the following year, typically after the AGM, seed is available to all our website visitors. For our most recent offer, follow this link - Seed List

The Society makes an annual offering of seed, which is free to its members. The varieties offered are usually not easy to find, and most, if not all, will have habitat information. Most often though, the seed offered will be second or later generation, owing to the ban of export of seed by the Mexican authorities.#, sourced from a vaiety of well known seed purveyors.


Our previous offers can be seen for reference:










Note: the seed list here cannot be used to order seed. Members please go to the Members area to find the correct form.
