The variety is intended for the dried fruit market. The tree is characterized by vigorous growth and regular fruiting. Fruit ripening occurs 7–14 days earlier than in the Improved French variety.
The fruits have a dark purple color with a medium wax bloom. They are larger and possess better flavor qualities compared to the Improved French variety. The variety is suitable for drying, but requires adaptation to existing industrial processing methods.
