The cornflower is therefore a messicolous plant. A messicolous plant is any plant that has adapted to human cultivation practices and whose development cycle is based on that of field-grown cereals. Today, these messicolous plants, which are becoming increasingly rare, make up the richness of our flora. They are all the more important because they are in danger of disappearing as a result of modern cultivation methods, to which they are very sensitive, such as seed sorting, mechanical weeding and the use of herbicides.


Additional information

Habitat and botanical description

The cornflower is an annual or biennial messicolous plant that can grow up to 80cm tall, with lanceolate or pennate, hairy, light grey leaves and pretty flower heads, usually deep blue, sometimes purple or white. It flowers from May and for much of the summer. A common plant in cereal fields and some meadows and woodland margins, it prefers slightly acid clayey-sandy soils and likes the sun.

Mythology / History / Anecdotes and traditional virtues

According to Greek mythology, the cornflower takes its botanical name Centaurea from the centaur Chiron, who was wounded by a poisoned arrow and healed by the plant's juice.
In the language of flowers, the cornflower symbolises the modesty and shyness of a budding love affair, but also fidelity. A young girl wishing to marry would wear it in her hair, and a young man looking for his soul mate would decorate his buttonhole with it.
This wild flower was also chosen as the national symbol of remembrance during the First World War, a flower that continued to grow on the battlefields and whose name was given by the Poilus to the young new soldiers who wore the horizon blue uniforms.
Its nickname "spectacle breaker" is attributed to its effectiveness in treating eye problems.
