Touffues avec des fleurs à collerettes.

Sow 6mm (¼in) 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. Transplant all the seedlings as certain colours tend to be stronger than others. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost 30x46cm (12x18in) apart in a sunny spot on any good moisture retentive soil.
