This small cactus appears above the ground as a squat, spherical stem, centrally depressed, completely covered by flattened spines, & usually solitary. in cultivation the plant’s stem may be cylindrical, & it will eventually produce clustering off-shoots with age. The species is classified as endangered because of habitat destruction, grazing of livestock, mining rock for construction, & dumping of rubbish. Actually the illegal extraction & trade of the plant doesn’t seem to be a real threat, because artificial propagation is not a problem today, & many nurseries produce the species. All seeds are fresh of this season & obtained from my personal collection. (NOTE: cactus seeds could be sown in any season under control environment, however if you wanna go with nature then best time to sow the seeds is early spring/summer ) (check my collection at https://www.instagram.com/planetcactus Mammillaria Pectinifera | 10 Seeds
