Duke of York seed potatoes are an old heritage potato variety, first entered on the national list back in 1891. Since their introduction, Duke of York have become famous for their great taste and all-round culinary ability. These seed potatoes are oval shaped with yellow flesh. Once they are boiled, Duke of Yorks are dry and mealy, making them an ideal variety to boil straight from your garden. They also show good resistance to dry rot. First earlies are typically ready for harvesting around 13-15 weeks from planting.
