Called "Sisu azul" from Lake Titicaca, this species shows high resistance against late blight.The Ecos purple potato shows good frost resistance in the ground and naturally produces a perennial type potato able to reproduce without replanting. Vines can spread 5-10 ft. in one direction. 'Perennializing' this potato works best in drier mineral like soil similar to the alpine environment of its home. Our plantings have always reproduced to some extent over winter where the smaller tubers often survive in frozen soil. We have one 10 year old planting on a open hill where it 'persists' and in competition the tubers shrink to half their size compared to garden grown. This potato has a great flavor similar to many fingerlings and is perfect for potato salad, soup or mashed.
This selection was given to us 25 years ago from a horticulture professor as a cast away in a breeding program. It has always been a reliable producer no matter what mother nature throws at it. It rarely has Colorado potato beetle damage and does not suffer from drought.
This selection can be fall or spring planted in the north. We recommend spring planting as this will allow the colony to get more fully established. If you live in an area with little frozen soil or are planting near the foundation of a house or protected area fall planting is fine. We are currently producing it for fall of 2020.
