The tree is vigorous, forming a wide, spreading crown of medium density. The variety is characterized by a relatively late onset of fruiting and is partially self-fertile. The presence of pollinator varieties is recommended for a stable yield.
Fruits are medium-sized, weighing about 32 g, and are round-oval in shape. The skin is dark blue with a thick waxy bloom and numerous light subcutaneous dots. The flesh is greenish-yellow, juicy, and tender. The pit is quite large and free-separating.
The variety matures in late August – September. It is distinguished by high winter hardiness, but is susceptible to fungal diseases, in particular fruit rot.
