Variety description

10 August 2026

The bush has vigorous canes 3 to 6 meters long. The variety shows good immunity to diseases and pests, but has medium winter hardiness and requires covering when grown in regions with cold winters.

Berries weighing 5–7 grams acquire a blandly sweet taste upon full ripening. The transportability of the fruit is assessed as low if they have reached full maturity. The variety is used both for commercial purposes and for home cultivation, including freezing and processing of the berries.
