My Pretty Rose Tree - William Blake

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.
