How to grow

Cultivation

Under glass, grow in peat-free, loam-based potting compost with additional leaf mould, in bright filtered or bright indirect light. In summer, water liberally, applying a quarter-strength fertiliser every third watering. Keep dry in winter. Outdoors, grow in moist, well-drained humus-rich soil in a sheltered site, and provide partial shade in summer. Mulch in winter, or alternatively, lift and store in a dry and frost-free place.

Propagation

Propagate by division in early spring.
