Sow February to April. Sow seed on the surface of lightly firmed, moist seed compost in pots or trays and cover with a fine sprinkling of compost or vermiculite. Seal container inside a polythene bag and keep at a temperature of between 18-20C (64-68F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination usually takes 21 to 30 days.

When large enough to handle, transplant seedlings into 7.5cm (3 inch) pots or trays. Gradually acclimatise young plants to outdoor conditions for 10 to 15 days before planting out after all risk of frost, 23-30cm (9-12 inches) apart.

For best results, provide any ordinary, well-drained soil in full sun

Caution: Irritant to skin and eyes. Harmful if eaten.
