Who all gets boutonnieres?

I have never been to a wedding were the minister had one. Usually only people in the bridal party, parents, grandparents and people directly involved in the wedding get flowers. I would save the money and not give one to people that really don't need them. To me ushers would wear them, great aunts probably not unless you are really close to them.

@alliecat- no one ever said the minister wasn't am important part of the wedding.

At least offer!! Though your wedding officiant is (or at least should be) compensated for his or her services, the wedding officiant is a vital member of your wedding party with the most important and significant role in the wedding ceremony. He or she should be invited to be in your wedding photos and should be appropriately dressed to match the wedding party (including a boutineer).
