Elena I haven't thought about petunias. I had them years ago and the middle would thin out as the plant grew. I'm all about groundcover so I may try them again. I've also heard that certain clematis will make a blooming groundcover too. Snapdragons are a good idea also.
Cinta the shrubs you mentioned are small? I've never had peonies, I thought I was too far south for them. I've already gotten my sweet allysum seeds!
