The native cereal field herb, which used to be common, has now been largely displaced from our flora through the use of herbicides. The cornflower with its blue flowers is considered the epitome of idyllic, extensive agriculture. Height 30-80cm.
Sow widely in place from September to October or March to April.
Thrives in any open garden soil in a sunny location. No compost donations. Sow together with poppy seeds, Venus mirror, corn wheel and emmer.
