The perdrigon, occasionally spelt "perdigon", is an old variety of culinary plum originating in the south of France. It is sometimes classified as a variety of "Prunus domestica" subsp. "insititia", like the British damson and German "krieche", though it has significant differences from both. It was once classed as "Prunus pertigona" or "Prunus domestica pertigona".
