  • Common name: Cactus
  • Family: Cactaceae
  • Plant Type: Cactus or succulent, House plant, Evergreen
Foliage colour:


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 geminispina bears cylindrical stems covered in white spines with fine down. Pink flowers appear in spring. Slow-growing, it eventually develops into a huge mat of clustered stems, but takes some years to do so.


For best results grow Mammillaria geminispina 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.
