I totally agree with the way Neal places and blends coral roses. Rather than try to match them up with other roses, I place them with grasses, shrubs, and trees with burgundy foliage. I'll try to find a picture or list of what I use--there's a good variety of plants that combine peacefully with coral tones.
In a way, it's a bit like picking a sweater to go with a dress, or jewelry. My closet has a lot of coral and pink, just like the garden!
