Answer: There are literally hundreds of annuals and perennials that grow well in your region! Rather than try to list them all, here's a publication from the University of Florida that not only lists the best, but explains the growing conditions, flower color and plant size. I think you will find it helpful in planning your colorful flower beds: http://edis.ifas.ufl.edu/pdffiles/MG/MG03500.pdf
Enjoy your garden!
