Interesting.
Way back in the days of the dinosaurs, when it comes to the exhibition name of a rose, I was taught I must refer to the current version of Modern Roses put out by the ARS, or the little ARS handbook for the year which would be even more up-to-date. It was the gold standard here in the USA for names when I was a rose judge. If someone didn't use the name in that book, they couldn't enter the rose in any ARS affiliated rose show. No matter how gorgeous a rose, if the name was wrong, it was disqualified.
I've been assuming that is what is used for the ATP database?
The closest thing I've found online available to non-ARS members is HMF, but I have noticed a couple of mistakes.
