Which, by the way, is the reason that the bees 

 produce, for themselves and for us, clover honey, 

 and orange honey, and onion honey, each with a 

 distinct flavor of its own. 



But there are other reasons why the flowers do 

 not get mixed up. 



One is that while some flowers advertise to the 

 bees, others advertise only to the humming birds 

 — the bees can not get into the bird flowers and
