Mammillaria hahniana Origin Central Maxico Family Cactaceae Description Old Lady cactus (Mammillaria hahniana) is a solitary cactus with white fuzzy hair-like spines and purplish red flowers. It grows up to 10 inches (25 cm) tall and up to 20 inches (50 cm) broad. The name, Old lady cactus comes from the covering of grey hairs which protect it from the harsh desert sun in its native Mexico. Environment Mammillaria species like most cacti they're drought tolerant and need very little care and attention to grow well . Plenty of sunshine will keep this cacti more than happy. Provide bright, even light to encourage tight growth and flowering. Some shade during a hot summers day can be helpful to prevent sunburn. Allow the soil mix to become nearly dry between watering, but then water thoroughly. Suspend watering in the winter, but mist occasionally. Not enough sunlight and over-watering are common mistakes. Use pot with good drainage and a very porous potting media. Feed every 4 weeks with a high potassium fertiliser during summer Landscape Uses Suited for window sill and dish gardens
