O bonie was yon rosy brier,
That blooms sae fair frae haunt o' man;
And bonie she, and ah, how dear!
It shaded frae the e'enin sun.
Yon rosebuds in the morning dew,
How pure amang the leaves sae green;
But purer was the lover's vow
They witness'd in their shade yestreen.
All in its rude and prickly bower,
That crimson rose, how sweet and fair!
But love is far a sweeter flower
Amid life's thorny path o' care.
The pathless wild, and wimpling burn,
Wi' Chloris in my arms, be mine;
And I, the world, nor wish, nor scorn,
Its joys and griefs alike resign.
