Centaurea cyanus (Cornflower, Bachelor's button, Basket flower, Bluebottle, Boutonniere flower, Hurtsickle) is a small annual flowering plant in the family Asteraceae, native to Europe. (Cornflower is also a common, though incorrect name for chicory)
It is an annual plant growing to 40-90 cm tall, with grey-green branched stems. The leaves are lanceolate, 1-4 cm long. The flowers are most commonly an intense blue colour, produced in flowerheads (capitula) 1.5-3 cm diameter, with a ring of a few large, spreading ray florets surrounding a central cluster of disc florets. The blue pigment is protocyanin, which in roses is red.
In the past it often grew as a weed in crop fields. It is now endangered in its native habitat by agricultural intensification, particularly over-use of herbicides, destroying its habitat; in the United Kingdom it has declined from 264 sites to just 3 sites in the last 50 years. It is also however, through introduction as an ornamental plant in gardens and a seed contaminant in crop seeds, now naturalised in many other parts of the world, including North America and parts of Australia.
In folklore, cornflowers were worn by young men in love; if the flower faded too quickly, it was taken as a sign that the man's love was unrequited.
The Blue Cornflower has been the national flower of Estonia since 1968 and symbolizes daily bread to Estonians. It is also the symbol of the Estonian political party, Rahvaliit, the Finnish political party, National Coalition Party, and the Swedish political party, Liberal People's Party and has since the dawn of the 20th century been a symbol for liberalism and social liberalism in the nation. The Cornflower is also often seen as an inspiration for the romantic symbol of the Blue Flower.
The Blue Cornflower was the favourite flower of Kaiser Wilhelm I. Because of its ties to royalty, authors such as Theodor Fontane have used it, often sarcastically, to comment the social and political climate of the time.
In France it is the symbol of the 11th November 1918 armistice and, as such, a common symbol for veterans (especially the now defunct poilus of World War I), similar to the poppies worn in the United Kingdom.
The Crayola company manufactures a color of crayon called Cornflower.
The cornflower is also the symbol for Amyotrophic Lateral Sclerosis.
