Zinnia elegans 'Purple Prince' - Seeds

Sow March to May. Sow seeds on the surface of a good, free-draining, damp, seed sowing mix. Then lightly cover, 3mm (1/8in) deep with vermiculite or sowing mix. Place container in a propagator or seal inside a polythene bag at a temperature of 20-30C (68-86F) until after germination which usually takes 7-14 days. Can also be sown direct into the soil after last frost.

Transplant seedlings when large enough to handle, taking care not to damage the fragile roots, 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 30cm (12in) apart.
