Variety description

10 August 2026

The bush is vigorous, fast-growing, and upright, reaching a height of 1.3 to 2 meters. The variety possesses good winter hardiness, withstanding temperatures down to -29° C. General resistance to fungal diseases is noted, although susceptibility to stem canker and bacterial blight is possible under unfavorable conditions.

The berries are light blue, large, with firm flesh and a characteristic texture. The small, dry scar facilitates long-term storage and allows for mechanical harvesting. The variety is intended for fresh consumption and processing.
