Have a bride who is going with a roman theme for her wedding. They are going to be doing the centerpieces themselves with green and purple grapes everywhere. She is looking at doing green and purple for her flowers as well, but wants to keep the cost down. (way down, I am afraid) I checked on roman weddings and have seen a lot about using herbs? Don't think she would be interested in this, just flowers. Anyone have any good ideas using purple and green?
