It is a small globular cactus that tends to cluster at the base. It has well marked ribs with evident horizontal grooves and short, white spines. The color of its stem makes it very particular and fascinating: it can take on colors, ranging from green to brown or from dark green to bright red with wonderful yellow and pink variegations, which are unique for each specimen. In spring, it blooms with silky-looking flowers of a yellowish-green color.
