Jill, I've got Johnson grass here too, it's terrible! It's one of the 2 things that make me resort to roundup, the other being poison ivy. Fragrant Spreader is fairly fragrant, kinda reminds me of multiflora rose scent. There are still a few that I missed when I was digging them up, would you like them?
Debra, I've seen some drift Roses growing in the area, and they don't look quite as aggressive as Fragrant Spreader. I kinda doubt they would choke out Bermuda grass though. You may want to try layering cardboard and mulch on the area a few weeks before you plant the roses to smother the grass. It was a real pain trying to pull grass from around thorny, low growing roses, so you'll thank yourself for getting it under control beforehand.
