How to grow

Cultivation

Under glass, grow in peat-free, loam-based potting compost in full light. Water freely while in active growth and apply a balanced liquid fertiliser every 2 weeks. Keep barely moist in winter. Maintain a minimum winter temperature of about 5°C; the plants will lose their leaves but these will regrow in spring. Plants may be moved outdoors to a position in light, dappled shade in summer.
