This is the 'Peace' rose, which was christened by the Pacific Rose Society exhibition in Pasadena on the day Berlin fell. Provided to forty nine delegations of the United Nations with a single bloom. Peace aquired its name during world war II, and legend has it that budwood was flown out of Paris just before the Germans arrived there.
New plants offered for sale now seem to be more susceptible to blackspot.
The buds are very fat and open to a very large, full bloom. If this bloom is cut when only partially open and brought inside, it will be fairly fragrant when it opens up. The colors of the bloom can range from very pale yellow edged in pink to a deeper yellow with the pink color spreading accross the petals.
