Lovely Muggle!! Just love the Limelight Hydrangea, they are such a nice shape, even the leaves are different. I love hydrangeas, my grandparents used to have a hedge of them and the smell still reminds me of holidays I spent with them as a child. I have a couple of the ordinary ones beneath a large old camellia tree but was wondering how well they would grow next to roses. The roses are in a sunny position, so not sure if it would be too much for hydrangeas. You say you have them on three sides of the house, do any of them get a lot of sun?
