How to grow

Cultivation

Grow in containers in loam-based compost such as John Innes No. 3, water freely when in growth but sparingly in winter, and apply a balanced liquid fertilizer monthly from spring until flowering; in mild areas, grow outside in moisture-retentive but well-drained soil in full sun, and provide winter protection with a dry mulch; for more advice, see Agapanthus cultivation

Propagation

Propagate by division between spring and early summer, or in early autumn after plants have finished flowering

Suggested planting locations and garden types
  • Cottage and informal garden
  • Patio and container plants
  • City and courtyard gardens
  • Coastal
  • Gravel garden
  • Mediterranean climate plants
  • Cut flowers
  • Flower borders and beds
  • Wall side borders
Pruning

No pruning required except cutting back dead flower stems, but allow them to remain until spring, because the seedheads look attractive over winter

Pests

May be susceptible to slugs and snails and agapanthus gall midge but generally pest-free

Diseases

May be susceptible to a virus
