Mammillaria hahniana – Old Lady Cactus (17 cm Pot)
Plant Highlights: Soft white hair-like spines • Rounded, sculptural form • Ring of pink flowers in season • Compact and easy to care for • Ideal for bright windowsills and sunny rooms
Overview
Mammillaria hahniana, commonly known as the Old Lady Cactus, is a distinctive cactus prized for its spherical shape and dense covering of fine white, hair-like spines. The soft-looking covering gives the plant a unique appearance while helping to protect it from intense sunlight in its natural habitat.
When mature and grown in bright conditions, it can produce a crown of small, vibrant pink flowers around the top of the plant, creating an attractive contrast against the white spines. Its compact size and slow-growing habit make it an excellent choice for windowsills, desks and sunny indoor displays.

Growing Guide
Place in the brightest position available, such as a south- or west-facing windowsill, where it can receive several hours of direct sunlight each day.
Allow the compost to dry out completely between waterings, then water thoroughly and allow excess water to drain away. Reduce watering significantly during autumn and winter when growth naturally slows. Avoid leaving the plant sitting in water, as excessive moisture can lead to root rot.
Indoor Placement
Perfect for sunny windowsills, conservatories, home offices and bright living rooms. Its compact habit makes it easy to display on shelves or alongside other cacti and succulents.
Why We Love It
The combination of its soft, woolly appearance and neat rounded form makes Mammillaria hahniana one of the most recognisable cacti. With minimal care and plenty of sunshine, it rewards growers with years of architectural interest and, in time, charming rings of pink flowers.
