Beautiful Ginger but you need not worry as to whether Amaryllis crosses are released or not.The registration process is too expensive and time consuming for anyone but commercial companies to use.
They don't follow the same process we brug people do.
In the past some folks have given their crosses a name preceded by their name to let people know it is not commercially registered.I'm thinking of some like "Mr.Hughes" and some of Liz's crosses on which she uses a number along with her name....I think.
