Description: Mammillaria backebergiana is an attractive slender columnar cactus with yellowy or brownish-yellow spines and great purplish red flowers circling near the top of the plant during growing season. Two subspecies are recognized, the nominate and subsp. ernestii (Fittkau) Glass & R.A.Foster.
Similar species: Mammillaria backebergiana is related and similar to Mammillaria spinosissima and its allies, but its stems are more slender.
Habit: Plants usually solitary occasionally clumping.
Stem: Globose becoming cylindrical, to 30 cm high, 5-6 cm in diameter, clear green, waxy.
Tubercles: Short pyramidal, not angled, with latex, axils naked or with a few bristles.
Central spines: 1-3, straight, needle-like, yellowish brown to brown, 7-8 mm long.
Radial spines: (8-)10-12, yellowish white with brown tips, becoming darker with age, 8-10 mm long.
Flowers: Freely produced in several rings in the crown. Purplish red, 18-20 mm long, 10-13 mm in diameter. Stigmas green.
Fruits: Dull green above, whitish below, tinting purplish red in maturity.

Cultivation and Propagation: Mammillaria backegeriana is easily grown into clumps, but it does often have an irregular pattern of offsetting. Probably the greatest problem with growing this species is that it will become a tall column with age, and tend to lean or tip over its pot.
Growing rate: It is a relatively rapid growing and easily flowering species, it doesn't present any special challenges. Most plants will offset readily, and clumps can be produced in a few years.
Watering: Water regularly in summer, but do not overwater (Rot prone), keep dry in winter
Soil: Use pot with good drainage and a very porous potting media.
Fertilization: Feed with a high potassium fertilizer in summer.
Hardiness:* It is quite frost resistant if kept dry, hardy as low as -5° C.
Exposure: Outside full sun or afternoon shade, inside needs bright light, and some direct sun.
Propagation: Division, direct sow after last frost.
