The tree is medium-sized, reaching a height of 4–6 meters, and has a rounded or rounded-pyramidal crown of medium density. Fruits weighing up to 50 g have an elongated-ovate shape and are often asymmetrical. The dark purple skin is covered with a bluish waxy bloom. The yellow flesh has a granular structure and a honey flavor; the stone separates easily.
The variety is partially self-fertile and matures in late August — September. It possesses high winter hardiness, withstanding temperature drops down to -34°C, and resistance to Polystigma rubrum and plum pox virus, although it can be affected by black knot. Fruits tolerate transportation well and are suitable for fresh consumption, drying, and processing.
