For about three years I have planted from a packet labeled Zipper Cream Peas and I get as many as three varieties of field peas growing, The main one that is different is a small pea jammed in a pod about 5 inches long. And then for the most part the crop are the true zipper cream peas (large in much longer pods). I'm wondering if anyone else has experienced this and where I may be able to get seed that are all consistent and true to discription and name.
