about cornflowers

Centaurea cyanus, also known as cornflower or bachelor's button, is an annual flowering plant in the family Asteraceae native to Europe. In the past, it often grew as a weed in cornfields. It is now endangered in its native habitat thanks to the intensification in farming, particularly by over-use of herbicides.

in the records

Cornflowers were one of the national symbols of Germany. One of the reasons was from the time when Napoleon's army pursued Queen Louise of Prussia out of Berlin. To protect her children she hid them in a field of cornflowers. In order to distract them and keep them quiet, she made wreaths from the cornflowers. Since then, the cornflower has become associated with Prussia.
