The web site says "They are potatoes of the richest purple – purple skin and purple flesh, jam-packed with nutrients and antioxidants it makes a fantastic member of the superfood family along with blueberries, pomegranites and kale. With its genetic origins in the Andes, it’s been specially selected for the food market and has enjoyed great success. It’s an early maincrop variety suitable for salads, and of course as jackets which prove a real hit with children fascinated by its dark purple flesh."
My nieces children were amazed when I grew spuds that had purple skin on the outside, I can only imagine what they are going to be like when they see these are purple on the inside as well.
