This is the small English daisy, the “day's eye” in whose praise Chaucer wrote:
“Of all the floures in the mede,
Then love I most those floures white and redde;
Such as that men call Daisies in our town.”
Shakespeare mentions it in the song to spring at the end of Love's Labour Lost (V, ii, 9047):
“When daisies pied and violets blue
And lady-smocks all silver-white
And cuckoo-buds of yellow hue
Do paint the meadows with delight,
The cuckoo then, on every tree,
Mocks married men; for thus sings he,
Cuckoo;
Cuckoo, cuckoo: O, word of fear,
Unpleasing to a married ear!”
