Most of mine were here! I think the David Austins and the Hot Cocoa might be grafted, but are in a protected area. Hot Cocoa should do well for you. It is changeable with the amount of sun and the temperature. Right now it's a smoky orange, but when it cools off it is sometimes quite brown.
I've gotten roses from High Country Roses and Chamblees, although I didn't have very good luck with those from Chamblees. I suspect the difference in latitude was too great.
I have the best luck with ogrs, a rugosa named 'Hansa', the multitude of 'Dorothy Perkins' ramblers, species rugosas, a Scots briar, gallicas, which grow like crazy up here, but might not like your heat and humidity. I have some old centifolias, multiflora hybrids, and a couple that I just don't know.
Part of the reasoning behind grafting is that the base of the graft won't sucker. It also allows some delicate roses to be grown in colder zones. And, the roses die, so you have to buy more. At least that's the way I see it!
