Dear common flower, that grow'st beside the way, 

 Fringing the dusty road with harmless gold ! 



First pledge of blithesome May, 

 Which children pluck, and, full of pride, uphold — 



High-hearted buccaneers, o'erjoyed that they 

 An Eldorado in the grass have found. 



Which not the rich earth's ample round 

 May match in wealth ! — thou art more dear to me 

 Than all the prouder summer blooms may be. 



To the Dandelion — James Russell Lowell
