How to grow

Cultivation

Grow in a sheltered position in moderately fertile, well-drained, alkaline to neutral soil in full sun. Plants sometimes die off over winter to be replaced by new rosettes. See hardy cacti and succulent cultivation for further advice

Propagation

Propagate by softwood stem tip cuttings of non-flowering shoots. Flower shoots also produce new rosettes in the leaf axils, that drop to the soil and root
