Sowing – Germinate at 15-20C (59-68F) on the surface of a good free draining, damp seed compost. Cover with a very fine sprinkling of compost or vermiculite. Place in a propagator or seal container inside a polythene bag until after germination. Do not exclude light, as this helps germination.

Growing – Transplant seedlings when large enough to handle into trays or .5cm (3in) pots. Grow on in cooler conditions for 10-15 days before planting out after all risk of frost, 45cm (18in) apart.

Flowers – July to September
