The plant has moderate growth vigor and more compact dimensions compared to the «Barcelona» variety. Fruits ripen in the second half of September. The nuts have a regular round shape, a weight of 3.5–4.2 g, and are characterized by good kernel quality, which is easily blanched.
The variety is self-incompatible and requires the presence of pollinator varieties that bloom during the same period. The key advantage of the variety is its complete resistance to Eastern Filbert Blight caused by the fungus Anisogramma anomala. The plant is characterized by high winter hardiness down to -26...-28 °C.
