I really am not crazy about the idea of registering plants as seedling x seedling or unknown x unknown and have never done so. But, I have a super plant that I just registered that is an unknown x unknown. The tag faded, I was using industrial strength marker and it still faded. I now use paint pens. All I can say is that hybridizers try and use the very best material when hybridizing. I certainly have an idea what the cross is but because I can't say l00%, unfortunately it had to be an unknown x unknown. This one is quite possibly When Spirits Unite x Ed Brown.
