The plant is a shrub or tree of medium height with a dense spreading crown. Growth vigor is rated as medium to high. The nuts are round with a mass of about 2.5–3 g; their shell is thin, light brown, often with stripes.
The kernel percentage is 44–48%, with a single kernel mass of 1.2–1.4 g. Flowering occurs mid-season, and fruit ripening takes place in September. The variety shows resistance to big bud mite, frosts down to -20°C, and spring frosts.
The variety is self-pollinating; however, cross-pollination with other hazelnut varieties is recommended to increase productivity.
