The mother plant was recovered in the area of Gualdo Tadino (Perugia) and after that also in the area of Gubbio (Perugia). Its origin is unknown; isolated specimens used to be cultivated in the high hills of these areas. The plant is very vigorous, hardy and with a spreading habit. It is very productive and blooms late. The fruit It is small, roundish and flattened. The stem is long and bent. The calyx is small and not too deep. The skin is very thick and hardy to the touch, with a green background, and a russeting covering the whole fruit. The flesh is white, not too juicy and moderately granular. It is harvested in November, after the first frosts, and can be stored in the fruit-house in the straw. In this is way the fruit turns overripe and soft and its flesh brown and tender. It is a very hardy fruit and suitable for cooking and jamming. It is eaten fresh only if it is left to soften as it is done with sorb apples. The flavor of these pears is enhanced by cooking them with red wine of good quality, left whole and with their skin on, with a little bit of sugar as required, and aromatized with cinnamon and clove. Their name may come from the fact that foxes are greedy for these fruits.
