Looks like you already have those colors together in each of your florals. Your tone on tone green is brighter than the other greens, or is that just the photo? I don't see any blue, so are you wanting to bring the blue in?
I see large and medium prints so is it the small print you are looking for? I have lots of florals so will check once I know for sure what to look for. Smiles and hugsssssss
