Alaska Frostless

Great yielder of flat, round, yellowish-brown tubers with white flesh. I have to say, this potato lives up to its name. It is still green and growing here in zone 9a on January 3rd after multiple hard frosts. All the other potato varieties and tomatoes are long dead. Definitely has remarkable cold resistance. Never seen anything like it. Tuber photos from USDA GRIN database; photo of plant still growing in January taken by me in my garden.
