Variety description

10 August 2026

The bush of the variety reaches 1.2–1.8 m in height, characterized by upright shoots and moderate branching. The variety features an early ripening period starting from the second half of July and late flowering, which helps protect inflorescences from spring frosts.

The light blue berries have a diameter of 17–20 mm and a weight of 1.8–2.5 g. The fruits possess a sweet-wine taste with slight acidity, firm juicy flesh, and high transportability. The variety is winter-hardy, withstands temperatures down to –29…–34°C, and is resistant to diseases and pests.
