Colfiorito is in fact a trade name given to a Désirée potato grown in Colfiorito, a town in Umbria, Italy.
Growers there claim that Désirées taste their absolute best when raised in their particular climate zone, on the mountainous Appenine slopes.
Production is managed by the “Cooperativa Colfiorito.” The potatoes are often sold on the sides of the roads there, and in local markets where they are called “patate rosse” (red potatoes.)
It took the producers a while to get Italians used to the idea of “red-skinned” potatoes.
Good for making gnocchi with.
Colfiorito Red Potatoes were introduced (in a marketing sense) in the 1960s.
Received EU PGI designation in 1998.
