How to Grow

Cultivation

Grow in a bright position, out of direct sunlight in moist but well drained soil. If grown outside, choose a sheltered position against a south-facing wall. Feed during the growing season, stopping when the temperature drops or the plant becomes inactive. Avoid overwatering

Propagation

Propagate by removing the growing tips as cuttings in spring. This may prove to be difficult but worth trying

Suggested planting locations and garden types

  • Architectural
  • Conservatory and greenhouse
  • Wall side borders

Pruning

No pruning required, but to keep it compact, pinch out upward-facing growing shoots to encourage more bushy growth lower down the plant

Pests

May be susceptible to mealybugs, aphids, thrip and red spider mite

Diseases

May be susceptible to a leaf spot
