The Mammillaria Society makes an annual offering of seed, which is free to its members. Unfortunately due to Phytosanitary restrictions we can only offer these to UK 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. Seeds have been sourced from a variety of well known seed purveyors and from members. We welcome donations of seed or we can pay individuals if at least 100 seed of any species can be supplied. Please contact us if you wish to do so.
