Flowers floating in the river

We were walking by the river and ran into these flowers that were floating there by the shore. Couldn't pass them by without taking a picture or two. They kind of looked to me like they had been bridemaids bouquets (there were at least three of them floating around), although to have an ear of corn at the base of a bouquet is a little unusual. I can't imagine them taking their wedding photos by the river, so don't know how these got tossed in but Brownie and I sure enjoyed them. You just don't see that everyday.
