It was recovered in the area of Mucignano, in a number of different properties in the municipality area of Citta’ di Castello (Perugia). According to an old farmer who was still cultivating it, it may be a seedling ecotype, born inside the hollow trunk of a chestnut tree and propagated by various farmers in the surrounding area. It is highly valuable for the toughness of the plant and the excellent organoleptic characteristics of the fruit. It is suitable for cultivation in the mountains and in the high hills. The plant is vigorous, very hardy, with a spreading habit. It crops regularly and blooms mid-late season. The fruit is medium-large, globose-conical and symmetrical, with a long, thick stem, inserted in an acute and moderate cavity. It has a semi-open calyx. The skin is shiny, smooth, green but veering to yellow with a purplish tinge at ripening time. The lenticels are not too marked. The flesh is white, slightly sour, very aromatic and crisp and of excellent quality. This apple is traditionally harvested with the waning moon in October and stores very well until April. The ripening takes place in the fruit-house starting from November. To keep this and other varieties it is advisable to build a fruit-house: a place that is not too cold and not too warm, not too ventilated and facing east or south. If it meets these requirements, it can be a cellar or an attic. For storing the fruit some shelves made of wood and covered with paper, straw or well dried moss are needed; pears should be placed standing up while apples should be standing on the side of the stem. In any case the fruit must be dried well before being stored.
