Variety description

10 August 2026

The tree has a straight trunk shape with relatively thin branches. At a young age, the crown is narrow and dense, becoming wider over time. The leaves are deltoid in shape, their color changing from light green at bud break to dark, with subsequent yellowing in the autumn. The bark is gray and furrowed.

The variety is characterized by high winter hardiness (withstands frosts down to –28...–34 °C) and wind resistance, including resistance to sea winds. The plant is characterized by low sensitivity to bacterial canker and rust, as well as sufficiently high resistance to leaf spot. It adapts well to loess, heavy clay, and light loamy soils.
