Beauteous rose-bud, young and gay,
Blooming in thy early May,
Never may'st thou, lovely Flow'r,
Chilly shrink in sleety show'r!
Never Boreas' hoary path,
Never Eurus' pois'nous breath,
Never baleful stellar lights,
Taint thee with untimely blights!
Never, never reptile thief
Riot on thy virgin leaf!
Nor even Sol too fiercely view
Thy bosom blushing still with dew!
May'st thou long, sweet crimson gem,
Richly deck thy native stem;
Till some evening, sober, calm,
Dropping dews, and breathing balm,
While all around the woodland rings,
And every bird thy requiem sings;
Thou, amid the dirgeful sound,
Shed thy dying honours round,
And resign to parent earth
The loveliest form she e'er gave birth.
