Cornflower🌼
Cyanus segetum
ヤグルマギク
An annual or biennial in the daisy family, native to Europe. Once a common weed in wheat fields, it has declined and is now endangered in Germany. Introduced to Japan in the Meiji period for flowerbeds and cut flowers, and often self-sows. The Japanese name likens the flower to a 'yaguruma' (pinwheel decoration at the top of a carp streamer). The famous 'cornflower blue' has given its name to a colour and a dye. A national flower of Germany and associated with the Prussian royal family; in France, the symbol of remembrance for the fallen of WWI.
