Cornflower Blue

Sow indoors in Spring or Autumn. Can also be sown direct in spring when soil is warm, they take very well to direct sowing. Sow onto moist seed compost or sow direct into prepared, raked soil 0.5cm deep in drills 30cm apart. Thin to 15cm spacing when large enough to handle. Cover with a fine sprinkling of soil and keep moist. Germination takes 14-21 days. 

Transplant seedlings once large enough to handle to 8cm pots to grow on until ready to plant out, I like to ensure mine have at least two sets of true leaves, good root growth and are approx. 5cm high before planting out.  

To sow in Autumn plants can be overwintered undercover like in a greenhouse and then can be planted out the following Spring. Deadheading will encourage a long flowering season.

Plant outdoors after frosts. Full sun, any soil, although preference for chalky.
