Cornflower
Centaurea cyanus
France
Cornflower is a biennial plant flowering from May to September. The French gave it the popular name spectacle-breaker in the 17th century, as apothecaries used to crush cornflower flowers together with dew or rainwater for soothing sensitive or irritated eyes. Apart from having a therapeutic effect, it has been used cosmetically by women to give eyes a bright sparkling look.
