Gardeners' Notes:

Positive palmbob On Aug 20, 2010, palmbob from Acton, CA (Zone 8b) wrote:

this is a wonderful little cactus with dark skin, flat-topped tubercles covered with itty, bitty white spines that can hardly even be called spines, and no central spines... it is a totally 'user-friendly' plant that makes a beautiful potted specimen, even when not in flowers.. and the flowers are spectacular pink on its essentially black and white background. Has a huge root for a tiny cactus. From Coahuila, Mexico on limestone.
