The plant is a vigorous shrub. The fruits are large, uniform, oblate in shape, with an average weight of 3.2–3.5 g. The thin shell, 0.9–1.0 mm thick, is light brown or chestnut in color, and the kernel fits tightly inside it.
The variety is mid-season; the fruits ripen in the second half of August. The kernel yield is 43–47%, the fat content reaches 67–68%, and the protein content is 14.6%. The yield is at the level of 30–35 c/ha, and winter hardiness is medium.
The plant is characterized by comparative resistance to diseases and pests, in particular, it is weakly affected by powdery mildew. The variety is self-incompatible; it requires planting other pollinator varieties for fruiting. The bushes enter the fruiting stage early and bear fruit regularly.
