Description: Mammillaria supertextaSN|20905]]SN|20905]] is a clump forming cactus with small purple flowers in a ring around the sides of the stem. Its body is densely covered by crowded tubercles bearing short spines and abundant wool in their axils.
Habit: Simple at first, later branching basally and from the sides to form clumps.
Stem: Obovate to globose, green, 10-13 cm tall, 8-10 cm in diameter somewhat umbilicate at apex.
Tubercles: Small, 2-4 mm long, ovate to conical, crowded, not lactiferous. Axils very woolly, so that the tubercles are almost completely covered.
Spine-areoles: Tomentose when young.
Radial spines: 16-18, slender, stiff, bristle-like, chalky white, spreading lower ones longest, to 5 mm.
Central spines: Usually 2 (sometimes 1 or 3, occasionally missing), very short, less than 3 mm long, rigid, white with dark brown tips
Flowers: Small, lateral (rather than near apex) pale to deep purplish red.
Blooming season: It flowers in autumn (in habitat in November)
Fruits: Clavate bright red to crimson. They are 8 to 16 mm long and 3 to 5 mm thick. Seeds: Brown.
Chromosome number: 2n=22, x=11.

Mammillaria elegans var. supertexta (Mammillaria supertexta) Photo by: Carolina GonzálezCultivation and Propagation: It is a free-flowering and relatively easy plant to grow.
Exposition: Full sun to light shade.
Watering: Water regularly in summer but do not over-water. Keep dry in winter. Hardy down to -4°C.
Growing tips: It is better that they be repotted regularly. Repotting will increase the number and size of stems, and will increase the number of flowers produced. Repot yearly until it reaches about 3 cm in size, then every two or three years will suffice. Repotting is best done at the end of winter, but it can be done at other time, too. Do not water for a couple of weeks after repotting, in order to reduce risk of root rot via broken roots.
Propagation: Seeds or offsets if available.
