Answer: You may have tried standard petunias in the past, but if you haven't tried the new Wave series, I think you'll be pleasantly surprised. In your deep south location the new Wave series of petunia should do quite well in all but the coldest of years, and will keep on producing into the warm season.
Other great cool season options include nasturtiums, calendula, dianthus, pansies and their cousins viola, sweet peas, and snapdragons. Also, don't forget flowering cabbage and flowering kale. They look great throught the cool season and then send up attractive bloom stalks of yellow flowers in spring.
