Hi neighbor. MB, SC here. You can grow lots of perennial things; gardenia, crepe myrtle, coleus (overwinter cuttings inside as water sprouts, ditto for) impatiens - ok, they're really annuals - camelia, day lillies, daisies, mums, 4:00's, EE's, cyperus (running out of breath) and a gazillion more things.
want cuttings?
Grow what you love, experiment, have fun.
Your best solution would be to visit a local garden center or professional landscape supply. (Not the big box store like Lowes, Walmart and Home Depot)
Below is a link to a few in your area or try John Deere Landscapes
