Early-maturing variety, harvest is ready for picking in the middle or second half of July. The tree is characterized by weak to medium vigor, forming a sparse or broad pyramidal crown.
Fruits are large, weighing from 40 to 70 grams, round or oval in shape. The skin is violet-blue with a glaucous waxy bloom, the flesh is yellow-green, juicy, of medium firmness, and the stone is easily separated.
The variety is partially self-fertile and can be a pollinator for other varieties. Fruits are for table use with medium transportability, suitable for processing.
The plant is sensitive to fungal diseases, such as rust and Monilia, as well as to late spring frosts and cool rainy weather during flowering.
