Are beautiful and fair.

Longfellow wrote:

O flower de luce, bloom on, and let the river

Linger to kiss thy feet.

O flower of song, bloom on, and make forever

The world more fair and sweet.

Lowell wrote:

The cowslip startles in meadows green,

The buttercup catches the sun in its chalice,

And there’s never a blade or a flower too mean,
