'Bleuets' are cornflowers.
Weimershof lies on the southern part of the Kirchberg plateau, and several of its streets carry flower names, such as the Rue des Coquelicots (poppies). The cornflower once grew as a weed in grain fields, which gave it its English name; intensive farming has made it endangered in its native Europe. In France, cornflower badges sold on 11 November and 8 May help veterans and war victims.
