Mammillaria bombycina
"Silken Pincushion"

     Native of Mexico, Mammillaria bombycina is a pretty globular to slightly columnar cactus that offsets like crazy in cultivation. It is also a fast grower. Heads can be up to 8 inches high and 3 inches around. Offsets are easily rooted and the easiest way to propagate the plant. In winter tiny pink flowers adorn the stems in a ring around the top.
      . This one was only about two inches around when I planted it. It grew like crazy and put out several offsets by midsummer. I took the offsets and rooted them and by end of season it had put out some more. This is a late winter pic, it unfortunately kept trying to grow in the greenhouse so became a little etiolated. The lower picture is one of it's early offsets, allready flowering size by the end of the season. It bloomed in winter in my greenhouse.
