Zinnia marylandica 'Zahara Starlight Rose'

Sow March to May. Sow seed in individual pots or module trays of moist seed compost and cover with a very fine sprinkling of compost or vermiculite. Place container in a propagator or warm place, and keep at a temperature of between 20-25C (68-77F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination will usually take 10-24 days.

Can also be sown once the outdoor soil has warmed, 3mm (1/8in) deep in drills 30cm (12in) apart in well-cultivated soil which has been raked to a fine tilth. When large enough to handle, thin out seedlings to 23cm (9in) apart.

When well grown, gradually acclimatise young plants to outdoor conditions for a few weeks before planting out after all risk of frost, 23-30cm (9-12in) apart, taking care not to damage the root system.
