Mammillaria zeilmanniana (Mammillaria crinita f. zeilmanniana) Albiflora is a soft bodied, glossy green, globular cactus up to 5 inches (12 cm) tall and up to 3 inches (7.5 cm) in diameter. It has 4 (the upper 3 straight, the lowest hooked) reddish central spines and clusters of soft, hair-like, 15 to 18, white radial spines. The flowers are 2 cm across, creamy white, stigmas yellowish. Rings of flowers are present most of the year. When young this species has wooly areoles though when mature it has 13–15 radiant spine and 4 central spines one being hooked.
How to Grow and Care
These cacti are easy to propagate either from seed or using offsets (pups). The pups spring up in clusters around the base of the parent plant. To propagate them, remove them carefully using a very sharp, sterile blade, or simply pull them away.Lay the offsets on a clean paper towel in a sheltered, airy setting for a few days. This will allow a callus to form over the cut or area where the pup was separated from the parent plant.
When a callus has formed, you can put the pup into its own pot. Keep it in a warm, sheltered place with bright, indirect sunlight until it takes root. This may take a few days or a few weeks. Once the plant has established roots, you can treat it as a mature plant.
Growing Conditions
Light: Mammillaria species appreciate strong light, but many species dislike more than four hours of direct summer sunlight. Provide bright, even light for the best results.
Water: Allow the soil mix to become nearly dry between waterings, but then water thoroughly. Immaculate drainage is essential, so never let the pots sit in water. Suspend watering in the winter, but mist occasionally.
Hardiness:
Hardiness USDA zone 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
Soil: A rich, fast-draining cactus mix is ideal.
Fertilizer: During the growing season, fertilize with a cacti fertilizer mix. Suspend feeding during the dormant winter period.
Propagation
Mammillaria cacti can be propagated easily from offsets, which readily form in clusters around the base of the mother plant. To propagate, carefully remove the offset and allow the cut to dry on a paper towel for a few days. Depending on the size of the cut area, a callous will form over the cut surface.
Once the callous has formed, place the new plant in a pot with a potting soil mixture and keep in a warm place until new roots emerge. Once the plant is established, repot it into a regular container.
