A spreading succulent, forming grey-green rosettes to 5cm across of rounded leaves sometimes lightly tinted with pink, and sending out fine stolons that develop into new plants at the tips. Conical spikes of creamy yellow or white flowers are produced from the centre of mature rosettes in late summer; rosettes die off after flowering to be replaced by the growing offsets

How to Grow

Cultivation

Grow in well-drained soil in filtered light or part shade, with protection from hot sun. Plants dislike excess humidity and winter wet, and may benefit from overwintering in a cool greenhouse or cold frame to keep moisture levels down. May lose some foliage or die back to the ground in cold winters. See hardy cacti and succulent cultivation

Propagation

Propagate by division, separating offsets in spring
