I grew this rose for a few years in a spot with only about 4 hours of sun in the spring and fall (much more when the sun was directly overhead). There was seldom more than one rose at a time, and the plant eventually died. I planted a new one in a totally sunny location and was absolutely awed by the difference. Plant this one in as much sun as possible, as it's a beautiful rose!
Site rogersroses.com mentioned ‘Marcellin Champagnat’ and ‘Sacred Heart’ as synonyms of ‘Caroline de Monaco’. But that seems wrong, as Marcellin Champagnat, syn 'Sacred Heart' is a completely different rose (see in HMF).
Dear help me find, The rose "caroline de monaco" is not available from Roses Unlimited in Laurens, S.C. They do not carry this rose as I have tried to order it from them for two years in a row. I was told by the owner of the nursery that they do not carry it. Too bad..
