Thank-you to everyone for all this great information.
Frankly, I wouldn't care if it was the AIS, a European, or a worldwide organization that straightened out the naming mess. If I had Liv Tyler, I wouldn't want to walk into a nursery and see Comptess de Provence and think I was getting something I didn't already have. It takes away the spontaneity of buying a rose for me.. That can't be good for the industry if more people felt that way.
