Neal, I'm three zones warmer than you, but I thought I'd toss out those that have done well for me anyway. Where I can, I'm sending pictures of the plants so you can get an idea of how they grow for me. All have pretty flowers except for Francine, but she has her own charm.
-Francine Austin- not much scent to speak of, but a good landscaping shrub. Lower growing, reliable and tough.
-Gertrude Jekyll- upright w/out the arching branches, good scent, but just can't seem to get excited about it. I think I probably need to move her to a more accessible location where I can poke my nose in a flower as a walk by.
-Christopher Marlowe- very pretty, tightly packed flowers. A changeling from bud to flower. Kind of twiggy growth. Not too tall.
-Nefertiti- my favorite of the ones that I grow.. More like a FL
-Tea Clipper- Nice scent, arching growth. Very pretty peachy flowers.
-Radio Times- delicious fragrance.. arching shrub or great espaliered. Does as well on own roots as grafted.
