Known as the old lady cactus, Mammillaria hahniana forms globe-shaped stems covered in fine white spines and white down, from which a circle of pretty pink flowers appears in spring. It’s the perfect cactus for beginners and makes a fine addition to any cactus collection.

For best results grow Mammillaria hahniana in cactus compost in containers in full sun. Water from mid-spring to summer only, and feed once a month with a special cactus fertiliser. Like all cacti growing in a temperate climate, it’s best grown as a houseplant but containers may be moved to a sunny, sheltered patio in midsummer.
