The word ‘daisy’ comes from the Old English dæges-eage, meaning ‘day’s eye’; in Welsh, it is called ‘llygad y dydd’, ‘the eye of day’. This is because the flowers open at dawn, their heads tracking the sun’s progress across the sky. At dusk they slowly shut each ‘eye’ by turning their white petals inwards to make a cup shape. Daisies will only open in full sun, staying firmly closed in wet weather.
This is the origin of the saying ‘as fresh as a daisy’, meaning someone who has slept well and is bright and ready to face the morning.
