Sturdy, well-branched plants produce a mass of bright, fragrant flowers early in the season. Up to 60% of the plants will have fully double blooms ranging in colour from copper to burgundy and from lavender to yellow AND are perfect for cutting. Stocks Vintage Mixed is free flowering in borders or containers.
Sow seeds from February to April. Sow seeds on the surface of lightly firmed, moist seed compost in pots or trays and lightly cover the seeds with a thin layer of vermiculite. Place in a propagator or seal container in a polythene bag and put in 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 10-21 days.
When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost 30cm (12in) apart or into containers spaced 15cm (6in) apart.
For best results, provide a light, well-drained soil in full sun.
The stocks can not be selected for doubleness, so there will be a mixture of double and single flowering plants.
