Fenoglio water radishes (not be confused with cress) are an edible root vegetable of the Brassicaceae family, described as having a "a creamier texture with sweeter flesh than a common radish, and a pleasing aftertaste." This particular radish is local to the shores of Lake Crump, the product of decades of cross-breeding and modification by the scientist Santo Fenoglio.
The water radishes have elevated quantities of vitamins A and E, potassium, zinc, and iron. Owing to the specific climate and soil conditions demanded, the only bulk growers are situated in the Lake Crump region, though some limited farming of a softer breed in Poldaki have met with success.
