Variety description

10 August 2026

The tree has an upright crown shape. Enters fruiting in the 3–4th year after planting. To obtain a yield, the variety requires pollinators, among which are the Tracy Sun, Fortune, Green Sun, and Shiro varieties.

The fruit ripening period is late, usually late August or early September. The fruit is heart-shaped with dark blue, almost black skin and yellow flesh. The stone separates almost completely from the flesh.

The variety is suitable for fresh consumption and culinary processing, and tolerates transportation well. The fruit is not prone to shedding or cracking in rainy weather, however, signs of cold damage may appear during long-term storage at 0°C.
