Western European variety of medium ripening period of unknown origin. Since 1959, it has been included in the State Register of selection achievements approved for use in the Northern, Northwestern, Volga-Vyatka, and Eastern Siberian regions.

Medium-sized, spreading, dense, hemispherical bush. Growing shoots have a dull anthocyanic coloration at the top. Characteristically, long glandular hairs are present. Woody shoots are thick, curved, brittle, grayish in color. Buds are large, on a narrow pedicel, arranged parallel to the shoot.

Leaves are dense, rough, dark green, large, slightly concave, with a strongly elongated central lobe. Lateral lobes are close together, basal lobes are weakly developed. Teeth along the edge are large, serrated. The upper surface of the leaf blade is sparsely covered with glandular hairs, while the lower surface has a medium density of hairs. Leaf base is rounded.

Flowers are cup-shaped. Sepals are greenish with numerous light-purple veins, overlapping to form a continuous ring. Petals are round and small. The perianth tube is very weakly developed.

Taste is moderately acidic and pleasant. Berries are suitable for fresh consumption and processing. Chemical composition of berries: dry matter — 15.2%, total sugars — 7.8%, titratable acidity — 2.5%, ascorbic acid — 38.0 mg/100 g. They are characterized by high content of pectin and P-active substances.

High-yielding variety (7–8 kg/plant), medium self-fertility, medium winter hardiness, medium resistance to anthracnose and septoria, susceptible to damage by blackberry bud moth, gooseberry sawfly, and red gall aphid.
