Sowing Months Flowering Months
  • Sow seed on the surface of good free draining, damp seed compost, cover with a fine sprinkling of compost or vermiculite.
  • Place in a propagator or seal container inside a polythene bag and place at 20-25°C (68-77F) until after germination which takes 7-14 days. Do not exclude light as this helps germination.
  • Transplant seedlings when large enough to handle, into trays or 7.5cm (3in) pots.
  • Grow on in cooler conditions for 10-15 days before planting out after all risk of frost, 45cm (18in) apart.
