Hello, Pat. I agree that the 1917 date probably should be 1947, and I agree that something should be done to distinguish the people who name sports from the hybridizers of cultivars. In the Rose Database we do this by adding "Discovered by" to the name in the hybridizer field. Here's an example in the entry for 'Chicago Peace,' a sport of 'Peace.'
Rose (Rosa 'Chicago Peace')
If there are names that are disputed by various taxonomic experts, that is something that can be addressed in a plant comment. We have no room for that kind of information in our plant data fields.
