The tree of this variety is weak- or medium-growing and has an upright-spreading crown. The variety is early-ripening; fruit ripening occurs at the end of July.
The fruits are small or medium in size, with a round or oval shape. The skin is colored blue-black or dark blue and is covered with a glaucous waxy bloom. The flesh is golden-yellow in color, firm, juicy, and sweet. The variety is considered a dessert type and is universal in use.
The plant has high winter hardiness and is capable of bearing fruit in conditions of spring frosts. The variety is partially self-fertile; the presence of pollinator varieties contributes to an increase in yield.
