What is a Boutonniere ?

What is a boutonniere? Is it really necessary? We feel that it is absolutely an integral part of the wedding attire. Why should the groom be left out? He needs to be included. He needs a bouquet also. But don't be boxed in and just pick a simple arrangement. Why not let the boutonniere compliment the wedding bouquet? You guys can match and really take your attire to the next level. This way your groom can also be the center of attention with you.
