Mammillaria is a genus of spiny cacti native to the desert regions of Central America, particularly Mexico. Plants usually form clusters of spherical or columnar stems, and bear funnel-shaped flowers.
Mammillaria spinosissima bears bright pink flowers and spines. The central spines are a reddish-brown or yellow. Mammillaria spinosissima cristata is an unusual form, its wave-like, undulating stems give it its common name: brain cactus.
For best results grow Mammillaria spinosissima cristata 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. Best grown as a houseplant, it may be moved to a sunny, sheltered patio for summer.
