Solanum tuberosum 'Blue Danube'
potato 'Blue Danube'
A bushy perennial grown as an annual vegetable for its edible tubers. A fast-growing, early maincrop potato ready to lift in the autumn, with purple-black stems, dark, glossy green foliage and pretty purple flowers. The blue-skinned, white-fleshed, well-shaped tubers are perfect for roasting (some say 'the best roast potato ever'). Shows good resistance to blight and potato viruses
