Variety description

10 August 2026

The plant is vigorous, reaching a height of 3.5 to 7 meters, and forms a rounded or spreading crown. The nuts weigh 2.5–4 grams, have a dense, medium-thick brown shell, and are clustered in groups of 2–6.

The variety is self-incompatible and requires the presence of pollinators such as «Косфорд», «Галле», «Шедевр» or «Барселона». Fruiting begins in the 3rd–8th year depending on the propagation method, and the harvest period falls in late August – September.

The tree possesses high winter hardiness (down to –32 °C) and resistance to drought and heat. The kernels are noted for their quality and high oil content, amounting to 68–72%, which allows the variety to be used for both commercial cultivation and private gardening.
