Cactus Mammillaria backebergiana subs. ernestii (Fittkau) 

Mammillaria backebergiana subs. ernestii (Fittkau) is an attractive, slow-growing cactus recognized for its distinctive cylindrical shape and dense covering of spines. Native to the arid regions of Mexico, this species features elongated stems that can reach up to 30 cm in height and often form clumps over time. The cactus is characterized by numerous small, rounded tubercles, from which emerge both white radial spines and longer, darker central spines, giving it a bristly appearance. The contrast of white and brownish hues adds visual interest to the plant. In spring or summer, Mammillaria backebergiana subs. ernestii may produce small, delicate pink or red flowers arranged in a ring near the top of the stem, offering a vibrant touch of color.

This cactus is relatively easy to care for, thriving in bright, indirect sunlight and well-draining soil. It requires sparing watering, allowing the soil to dry out completely between waterings to prevent rot. Like most cacti, Mammillaria backebergiana subs. ernestii prefers warm, dry conditions and should be protected from frost and excessive humidity. During the growing season, occasional fertilization with a cactus-specific fertilizer can promote healthy growth and flowering. With its manageable size and simple care requirements, Mammillaria backebergiana subs. ernestii is an excellent choice for both beginner and experienced cactus enthusiasts looking to add distinctive beauty to their collection.
