They survive the very cold Vegas winters (zone 9a) when we get one to several cold snaps a year (20F). I do have them protected with frost cloth as I do with several of my other cactus during the winter. |

| Positive | On Feb 17, 2004, palmbob from Acton, CA (Zone 8b) wrote: Not a very spiny Mammillaria so the 'nipples' (for which the genus is named after) are noticable. Develops some cream colored 'snowy' tomentum on top of plant. Branches dichotomously slowly and can get up to 5" in diameter. Doesn't like much, if any, winter water. From Oaxaca Mexico. This plant has so many synonyms I can't begin to list them all (found about 14 so far) |
