| Description: This strange Mammillaria makes a nice and tangled cluster of fine crests. Brownish-green or purple in full sun exposure with fine soft white spines. |
Green on shade exposure this plant became brow-purple in full sun.
Cultivation: It is a relatively rapid growing species. This is easily grown into clumps, but it does often have an irregular pattern of offsetting. Water regularly in summer, but do not over-water (rot prone). Use a pot with good drainage and a very porous potting media. Keep dry in winter. Feed with a high potassium fertilizer in summer. It is quite frost resistant if kept dry, hardy as low as -5° C. Outside full sun or afternoon shade, inside it needs bright light, and some direct sun.
Propagation: By division of larger clumps or graft.
