William Blake - My Pretty Rose Tree

A flower was offered to me,
Such a flower as May never bore;
But I said 'I've a pretty rose tree,'
And I passed the sweet flower o'er.

Then I went to my pretty rose tree,
To tend her by day and by night;
But my rose turned away with jealousy,
And her thorns were my only delight.

William Blake
