It is a good suggestion from Joe to contact the hybridizer to see if this could possibly be an error on his website. Since the cultivar in question was registered in 2011, only the hybridizer can offer a change. There is a fee, and the change must be only to correct an orthographic ( spelling) error. I would not buy this as a spelling error. Everyone who registers, as you know, receives a copy of the registration data sheet WHEN they register. The registrant is urged to look over the data carefully to make sure it is correct and if they see an error, to let the registrar know immediately. THAT is the time to make changes. Sadly, I am convinced that some don't bother to check.
