How to Grow

Cultivation

Under glass, grow in peat-free compost in full light but with some protection from hot sun. Outdoors grow in any moist but well-drained soil in full sun. Water moderately in the growing season and apply a balanced fertiliser once a month. In the winter keep the rootball just moist

Propagation

Propagate by seed sown in containers in spring at 16-18C (61-64F). Take softwood cuttings or semi-ripe cuttings in summer

Suggested planting locations and garden types

  • City and courtyard gardens
  • Coastal
  • Cottage and informal garden
  • Patio and container plants
  • Wildlife gardens
  • Sub-tropical
  • Flower borders and beds
  • Conservatory and greenhouse

Pruning

Tip-prune shoots on young plants in early spring to promote bushy growth. Older leggy plants can gave their stems shortened by half in spring

Pests

Glasshouse whitefly may be a problem if grown under glass

Diseases

Generally problem free
