Johnny's sells Maine Certified Seed Potatoes. The process of seed potato certification involves field inspections throughout the growing season, to check for disease and to ensure that varieties are true to type, as well as a winter grow-out of the seed, to screen for disease contamination. Our organic seed potatoes are — in addition to the above — produced under certified-organic growing methods. See our Potato Varieties Comparison Chart to review size, shape, skin and flesh color, storability, and culinary use.
