How to grow

Cultivation

Grow under glass in a cool or temperate greenhouse or conservatory or as a houseplant in filtered light, in a standard cactus compost (or peat-free, John Innes No 2 with an added third of extra grit or fine gravel) and allow it to dry out almost completely between waterings; for more advice see houseplant cacti and succulent cultivation

Propagation

Propagate by seed, sown at 19-24°C in spring (it does not reproduce readily from seed) or take rosette stem-tip softwood cuttings in early summer; wait until calluses have formed, then insert in sandy compost and in moderate light at 18°C, and keep just moist until rooted
