Oh such wonderful ideas! Steve, I am saving your post in my great ideas folder.
I saw a Paradise rose today and it matches a mystery rose I have, so I think I'll go back for it and do just what you said- but with just 1 of the Barbra roses. Which kind of artemesia are you using? Tall, like Silver King, or shorter, like Silver Mound or Sea Foam?
I saw Claire Austin cl. at a nursery and didn't bring it home and I've been kicking myself ever since. I may have to take a day trip and go back for it, and this time I will buy 2. It will go on an arch that has Snow Goose on one side and James Galway cl on the other.
I love love love a good plant combination. It's the feeling I get listening to a symphony or the harmonies of Boyz II Men, a marching band or dance troupe. All give me a calm, happy feeling.
