Where did the Irish patato come from?

Answer 1

Potatoes were brought back from the English colonization of northern America The potato was first cultivated by northern American Indians and was brought back by Sir Walter Raleigh (with tobacco amongst other things). The queen had previously given Sir Raleigh an estate during the plantations in Ireland previously (where Anglo Irish lords were dispossessed of their land and titles and people loyal to the English crown were "planted" in their place). After his return from the new world Raleigh retired to his estate in Ireland and I can only assume brought the potato, since its a starchy tuber it was perfect for the peasants that worked the land, that way they could fill themselves up since usually they had little food.

Answer 2

The potato originally came from South America.
