Variety description

10 August 2026

The variety is early, with berry ripening occurring in the first half of September. The plant forms a creeping dwarf shrub up to 0.1–0.15 m tall and up to 0.5–0.8 m wide. Thin shoots are capable of rooting upon contact with the soil, and the small shiny leaves change color from dark green to bronze-red.

The berries have a mass of 0.7–1.0 g, a diameter of 17–18 mm, and a pear-shaped or bell-shaped form. Upon ripening, the fruits acquire a purple-violet hue and a sour-tart taste. The variety is distinguished by good keeping quality and frost resistance down to -26°С.
