How to Grow

Cultivation

Under glass, grow in a preferably acidic, peat-free, loam-based compost in full light. Water moderately when in growth during the spring summer and early autumn, sparingly at other times. Plants may be placed outside in the summer in frost-prone areas and brought back under cover in the autumn, where they should overwinter in cool temperatures and low atmospheric humidity

Propagation

Propagate by seed at 16-18°C after soaking for 24 hours in warm water. Divide rhizomes in early spring

Suggested planting locations and garden types

  • Patio and container plants
  • Sub-tropical

Pruning

Not usually required; old stems may be removed

Pests

May be susceptible to glasshouse red spider mite and glasshouse whitefly when grown under glass

Diseases
