Of course, for all we know, Summer Nights might be a new name for one of those "Peace" roses.
J&P has never listed a registration name for it, and those roses are suspicious. A few years ago they introduced 'Mesmerized.' They didn't list the registration name, but they couldn't resist saying that it was a former Rose of the Year. It turned out to be the 2006 rose 'Spellbound.' Someone must have consulted a thesaurus to come up with the new name.
