Maincrop variety, producing very distinctive, oval, red and yellow skinned tubers with yellow flesh. Creamy, fluffy texture when cooked and excellent distinctive flavour.
Scab resistant. Reddish-violet flowers.

Most fertile, well cultivated soils but dislikes very wet or heavy clay soil. Prefers a slightly acid rich soil with plenty of organic matter, the tubers can be subject to scab on limy, sandy or gravelly soils or those deficient in humus. Likes a sunny position.

From tubers.

Culinary vegetable. Much faster to cook than normal varieties. Good for boiling and as a salad potato. Contains high levels of carotenoids, beneficial to health.

other notes:
Developed at the Scottish Crop Research Institute, Invergowrie, Dundee, Scotland, registered in 2001. Specially bred for the UK and Northern European climate, using an original Peruvian species parent.

All the green parts of the plant, even green parts of exposed tubers, are poisonous, containing a toxic alkaloid called solanine.
