Thanks for the info Juli. Even if it was perfectly fine to do it, it didn't feel right to me to do it, and I would have never considered doing it without permission. I will check into it getting registered though after I get it moved to Idaho with me. I'd be more than willing to pay for the registration because I adore it! There may be another reason why the person who grew it first doesn't want it registered, but from what I was told, it was only because of the cost, Even with mystery parents, it's worth it to me to help with the registration.
