Propagation
Surface sow fresh seed from spring to summer in pots and cover them finely with quartz grit, then moisten. Lay piece of glass over the pot and maintain a temperature of 10º to 20º C. (50º to 68º F). Remove glass after germination, and then prick out when large enough to handle and pot up.

Take cuttings during the growing period by removing a piece of the stem and allowing it to lay aside for a few days so the protective skin can form over the cut.  Plant up into a well-drained media, where they receive ample light and water sparingly at first.  As roots develop the plant may be watered more regularly, but never allow the soil to be constantly wet.
Divide the clump during summer.

Botanic information
Leaf: The conical tubercles have areoles with glands and 14-16 spreading or recurved straw coloured radial spines that are up to 10 mm (⅜ in ) long. The 2-4 greyish stout central spines are up to 90 mm (3½ in) long and erect or spreading with a pungent apex.

Flower: The solitary purplish-pink funnelform flowers have broad petals that may be striped in darker pink and appear towards the top of the plant during the night (diurnal) in midsummer. 

Fruit: The yellow-brown berry splits open when ripe from a basal pore and should be overripe before harvesting the seeds. The small warty black soft seeds are pitted and are viable but the plant may be reproduced vegetatively.
