Potatoes of the same variety, grown elsewhere are known as international kidney potatoes.
In around 1880 a Jersey farmer, Hugh de la Haye, showed friends a large potato that he had bought. It had 15 'eyes': points from which new plants sprout. They cut this potato into pieces, which they planted in a côtil (a steeply sloping field) above the Bellozanne valley. One plant produced kidney-shaped potatoes, with a paper-thin skin, which they called the Jersey Royal Fluke. This was later shortened to Jersey Royal.
In 2012, 28,600 tonnes of the potato, worth £28.6m, were exported from the island. This figure was down from 30,890 tonnes in 2011.
