I bought this plant from Lowe’s on clearance on September 21, 2018. The label says: 

“A globular cactus, usually solitary and growing to 6” height and sometimes to 8” in diameter. Spine color is highly variable with whitish wool and bristles at axils. Rings of reddish-violet flowers appear in April and May. Native of Oaxaca, Mexico. Protect from frost. Provide bright light/sun; hardy to 20° F. Water thoroughly when soil is dry.” 

The plant is growing in a 4 oz. (2 1/2” diameter x 2 1/4” tall) pot. The plant measures approximately 1 3/4” tall x 2 1/4” wide without the spines.

Mammillaria mystax is a neat small cactus with very pronounced tubercles. In the wild, it produces very long entangled spines on its crown. This species also divides dichotomically which means the stem divides to become two. It will produce a ring of rose flowers with brown mid-veins, up to 3 rows, February through April. The top areoles are wool covered but seem to disappear with age.
