I've enlarged and redesigned a flower bed. Although it has a few other shrubs that I moved from other areas and some lantana for summer color while the bed is getting established, it primarily has peach and coral roses with artemesia. The first 2 photos are from May when I planted the roses, and the 3rd one is from today. What color and variety of clematis would you recommend I add to this bed? I'd like to make sure the clematis do show up well against the white fence.
