For best results, provide a sunny, sheltered site and a deep, fertile, well-drained soil.

Caution: Irritant to skin and eyes. Harmful if eaten.
Sow seeds February to April. Sow seeds on the surface of a good free draining, damp seed compost and cover with a light sprinkling of vermiculite. Seal container inside a polythene bag or place in a propagator at a temperature of 10-15C (50-59F) until after germination which can take 21-40 days. Do not exclude light, as this helps germination.

Transplant seedlings when large enough to handle into trays or 7.5cm (3in) pots. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost, 60cm (24in) apart.
