For some reason, I was under the impression that these were the same cultivar with different names. The Wiki says that Pappey is a sport from Mammie and is also known as Nancy. Curious as to why there are no photos of Pappey or Congo found in the Wiki. There surely has to be some photos of these cultivars available. They are not very rare. I have a cultivar that may be Pappey, but I am not all that sure now. A certain box store has Congo from time to time, just can't remember what it looks like. Any help here?
