Brilliant, pure sky blue flowers blending magnificently ,with herbaceous and low growing shrubs and conifers or contrast with yellow, silver and white. Medium- large flowers in great profusion from spring to late summer and autumn.
Sow February to April for summer flowering, June to August for flowering the following spring. Sow 1.5mm (1/16in) deep in a good seed compost, excluding light as darkness is beneficial. Germination takes 14-21 days at 15-18C (60-65F). Keep the soil moist and avoid high temperatures which will prevent germination.
Summer sowings should be moved to a cold frame and planted out in early spring.
