I wonder how could New Zealand Crown Princess Mary be different from Australian version? I have a shrub with lemony creamy, very full flowers. They are divinely fragrant. I feel those two are two different roses. Can any one explain this please?
Someone’s sloppy record keeping. The New Zealand Rose Review 2019 shows an advertisement from GardenBarn in Masterton and the yellow picture is labelled there ‘Crown Princess Mary’. I wouldn’t mind betting that the yellow rose is, in fact, George Thomson’s 2001 rose ‘Philadelphia’.
