Daisies

In Old English, daisies were referred to as “day’s eye” because at night the petals close over the yellow centre and during the day they re-open. The phrase “as fresh as a daisy” originated from this, signifying that someone had a good night’s rest. All I know is they are beautiful.
"The splendor of the rose and the whiteness of the lily do not rob the little violet of it's scent nor the daisy of its simple charm. If every tiny flower wanted to be a rose, spring would lose its loveliness."  
Therese of Lisieux
