Gardeners' Notes:

A beautiful and charismatic little cactus with soft, pettable spines (just stiff hairs really), but it's extremely sensitive to overwatering. Hence in my rainy part of the world (Louisiana), I wouldn't even consider keeping it outside, unless it's under a porch roof so that you can control how much water it gets. Better yet, keep it indoors by a bright window year-round. Pups can be easily "snapped" off and potted up.

A beautiful white spined clumper. One of the most pettable cacti I've come across since Mammillaria plumosa. Impossible to stick yourself with it's soft velvety spines.
