Katie, my understanding is that OGW’s “Praire” series are trademarked names for Jim Claypool’s varieties. I believe Praire Dawn is H63A. Does anyone know what the others are? I tasted H63A recently and it was truly excellent. Also great is NB-02 (Zima Khurma) which Cliff England sells…I thought it was among best of what I tasted, along with Kasandra, which is another hybrid. Kasandra holds its fruit and has the taste of a kaki, but with some extra complexity. I have a Kasandra now, but I’m hoping to one day get a few others.
