Flowers? Go silk! Do-it yourself and craft stores are wonderful! Have to have fresh? Pick your favorite fresh flower and simply carry that single flower. Who says you have to have a bouquet? It's your wedding.
This example is a single sunflower, some greenery, tissue paper or netting/tulle can be used, and a pretty ribbon to tie it all together. (before wrapping the tissue paper and ribbon around it, it would be wise to tie the sunflower and greenery together, then wrap it.) Any large single flower will do.
Have some growing in your yard? Use those! Just make sure you cut them the day before. Put them in water and stick it in the fridge. NOT the freezer!!! Freezers kill flowers! Seriously, they turn the flowers brown!
