The best-ever basket petunia from seed! Petunia Rose Vein Velvet is the latest colour in the velvet series and promises to be as impressive! Like the others in the series, Rose Vein Velvet will out-perform expensive cutting raised Surfinia petunias. The lovely trailing stems, up to 1m (3ft) in length, look fantastic in baskets, window boxes and other containers where they will be continuously smothered in blooms all summer long. Also makes useful and attractive ground cover.
Sow February to April. Sow seed on the surface of lightly firmed, moist seed compost in pots or trays. Lightly cover the seed with a fine sprinkling of vermiculite. Place in a propagator or warm place, and keep at a temperature of between 21-25C (70-75F). 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 to outdoor conditions for a few weeks before planting out after all risk of frost, 30cm (12in) apart, or plant into containers.
