The thing about registration is the name that is registered is the official name of one cultivar, anything else with the same garden name is really an unknown no matter how nice.
So unless somebody has it reserved "Intelligent Rosemary" could probably be used for another plant.
And wouldn't that muddle up some of the long crosses that the unregistered Intelligent Rosemary is already named as parent
I have one that I really like a bunch from named Ryan Cobb, this was from a hybridzer named Webster, don't know his first name.
What happened here was that the name was preregistered, but Webster died before it could be registered, and it is being sold as Ryan Cobb with a bunch of misleading info on registration, it is not listed in the AHS
