Data on the origin of the variety are contradictory: sources indicate both Italian and American breeding. The official registration of the variety is associated with the Lithuanian Institute of Horticulture (LAMMC), however, detailed information regarding its breeding and parent forms is not publicly available.
Characteristics of the variety vary significantly in publications: the ripening period ranges from the beginning to the end of September. Fruits are described as elongated-ovoid, with a weight from 30–35 g to 80–100 g. The tree is characterized as medium-growing or vigorous with a rounded crown, while the claimed high winter hardiness and disease resistance lack documented scientific confirmation.
