Variety description

10 August 2026

The plant is vigorous, forming 2–5 flower stalks on each crown. The variety is characterized by the presence of male sterility in some flowers, which requires interplanting with pollinator varieties to increase yield.

Berries are dark red, glossy, large, with firm, uniformly colored flesh, suitable for storage for up to 5 days at room temperature. The variety ripens 5–7 days after the «Bounty» variety and 10–12 days after «Elsanta».

Plants possess high winter hardiness down to -30°C in the presence of mulch, are resistant to powdery mildew, gray mold, and terbacil, and show partial resistance to leaf spots. They adapt well to various soil types.
