For some reason Blue Girls work well for Toni. I've tried three of them over seveal years and have eventually gotten rid of each one because their blooms look and smell wonderful -- for about ten minutes in my garden. Then they quickly turn brownish and mucky.
As for ground cover roses, I grow a very large, sprawling Red Ribbons that is truly a continuous bloomer, just beneath a dwarf, bonsai-like pine tree on a sloped rock garden. They look great together.
