ROUGHWOOD/EFN EXCLUSIVE. Tomatoes across the Americas are known as "Riñon", which means kidney, but the earliest in the USDA's collection came from Cuba in 1932. Already less then uniform when it was collected from the wild in Cuba, nearly a century in the USDA's collection seems to have made the government's accession of the variety even more variable. When we first grew it out, we found at least a dozen different types, ranging in size, shape, flavor, color, and vigor. With a little selection, EFN co-founder Dusty Hinz has stabilized this wonderful little tomato from the 'Riñon' genepool: a reddish-pink, flat, fasciated (deeply ribbed), flavorful and incredibly productive tomato. Grown ecologically in New Jersey by the Experimental Farm Network.
