A breeding breakthrough, a true first year flowering perennial Coreopsis, ideal for planting in containers, window boxes or towards the front of borders. Naturally dwarf and compact ball-shaped plants are smothered in double golden yellow blooms all summer.
Sow February to March. Sow seed on the surface of lightly firmed, moist seed compost in pots or trays. Lightly cover seed with a sprinkling of compost or vermiculite. Place 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 21-30 days. When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays.
For best results, provide any ordinary, well-drained soil in full sun.
