Autumn blooms needed for a wedding next year

Autumn blooms needed for a wedding next year

I am getting married next year in the Fall on 10/10/10 in my home in Nashville. I am wondering if anybody in this area knows what flowers, bushes, etc will be blooming at this time. I'm hoping to try and grow all or most of the flowers that I would need for the wedding as a way of keeping costs down, and our theme is basically anything to do with autumn, so we're not planning on having any out of season flowers being displayed. Does anybody have any suggestions on flowers that are easy to grow outdoors, no greenhouse, very little fuss, potentially drought resistant, hardy little things that will survive the summer and bloom in early October in the middle Tennessee area?
