Souvenier de la Malmaison is my most fragrant rose. It is borderline hardy here, but with babying it is still hanging in there!
Tiffany hybrid tea (on its own roots) is also very fragrant . It is my favorite classic rose - and it also needs babying to get thru the winters and fight the blackspot in the summers. I grow Lagerfeld, but he is such a diva he only had one bloom last season. It was pretty and fragrant, but really. Yves St. Laurent is a beautiful hybrid tea pink rose. I don't grow it, but I LOVE the blooms. In a warm climate, you could probably grow some of the florist roses that I don't dare try here.
My Austins aren't as fragrant as the others, but they have lots of beautiful blooms.
In zone 11, you could grow antique and tea roses that I can't dream of growing here. Maybe Melva will chime in. She grows (and sells) lots of antique roses in Texas.
You may want to ask the experts here about root stocks for your climate. I know that people in Florida have problems with certain root stocks in their hot, humid climate. I have the opposite problem with some rootstocks not being winter hardy here - especially when exposed to the freeze thaw cycles and winter/late spring wet. Growing own root roses has been working well for me.
You can also grow Jasmine and Gardenia which I have to overwinter inside.
