Variety description

10 August 2026

The tree forms a pronounced central leader and reaches a height of 16–25 meters with a crown width of 6–8 meters. The leaves are narrowly elliptic, 5–10 cm long, glossy, dark green, turning yellow in autumn. The furrowed bark reveals an orange inner layer.

The variety possesses resistance to Dutch elm disease and Verticillium wilt, although its susceptibility to these pathogens may vary. In the USA, the variety exhibits high sensitivity to the elm leaf beetle.
