Coreopsis - Grandiflora Early Sunrise
Uniform plants will shine out from your borders with masses of golden yellow, semi-double blooms attracting beneficial insects all summer. This is a first year flowering perennial quickly coming into flower in as little as 12 weeks from sowing the seed.
Sow seed on the surface of the compost and cover with a very fine sprinkling of dry vermiculite or finely sieved compost. When the seedlings are large enough to handle, transplant each seedling into a 7.5cm pot or multi-cell tray. Before planting out, acclimatise plants to cooler conditions by putting outside during the day for a few weeks.
