Mammillaria mystax Mart. is the correct and accepted name for this species. It was named and described by Carl (Karl) Friedrich Philipp von Martius in Hortus Regius Monacensis in 1829.
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.
Origin: South Central Mexico
Zones: USDA Zones 9a-11 (20-40° F)
Size: Up about 6” tall x about 4” diameter.
Light: Sun to part shade
Soil: Very well-draining. Potting soil amended with additional grit and pumice or perlite.
Water: Regular watering during the summer and barely to none during the winter.
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.
