Sowing Months Flowering Months
Sow 6mm (0.25in) deep late winter to early spring at 21-24C (70-75F) in a good seed compost. Keep soil damp but not wet, sealing in a polythene bag after sowing is helpful. Germination usually takes 7-10 days.

When seedlings are large enough to handle, transplant and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost 30cm (12in) apart in a sunny spot on any good moisture retentive soil.
