Coreopsis x hybrida 'Incredible' really lives up to its name with unique, never before seen colours in an annual coreopsis. This easy-to-grow mixture produces masses of flowers in a remarkable range of colours with contrasting dark centres. Tall and airy Tickseed plants are ideal grown in mixed borders where the graceful stems and delicate blooms sway in the slightest breeze. Coreopsis flowers are also superb for cutting for an indoor arrangement. Height: 120cm (47"). Spread: 45cm (18").
Sow coreopsis from February to March on the surface of a good seed compost and lightly cover with a sprinkling of compost or vermiculite. Place the seed tray in a propagator at a temperature of 20-25C (68-77F) or seal it inside a polythene bag. Keep the soil damp but not wet. Do not exclude light as this aids germination which usually takes 21-30 days.
When seedlings are large enough to handle, transplant and grow them on in cooler conditions until large enough to plant outdoors. When Coreopsis plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over 7 to 10 days. Transplant outdoors in full sun in any well drained soil at a distance of 30cm (12") apart.
