How to Grow

Cultivation

Plant out seedlings 20-30cm apart after the final spring frost in well-drained but moisture-retentive humus-rich soil in full sun or very light dappled shade, and provide support. See sweetpea cultivation

Propagation

Propagate by seed: in milder areas sow during autumn, and overwinter the young plants in a cold frame or unheated glasshouse, or in colder areas sow in late March or April. Plant out when risk of frost has passed

Suggested planting locations and garden types

  • City and courtyard gardens
  • Cottage and informal garden
  • Patio and container plants
  • Climber and wall shrubs
  • Cut flowers
  • Flower borders and beds
  • Wall side borders

Pruning

Cut regularly to encourage more flowers; allowing seed pods to form will stop plants from flowering

Pests

May be susceptible to aphids, slugs and snails

Diseases

May be susceptible to powdery mildews, Fusarium wilt and sweet pea viruses
