Wedding Flowers Dayton Ohio

I'm getting married in August, which would be the best type of flowers for an outdoor wedding?

Where can I find in / Xenia Dayton Area Ohio? Need really cheap!

I did the makeup for a wedding a few years out of Alog in the middle of August, which had a beautiful variety of wildflowers, including Susan Margaret White, black, orange and some flowers. I guess that depends on the color of bridesmaids dresses.
