10 August 2026
The variety is a vigorous shrub with a dense spreading crown, reaching 4–6 meters in height and width. The leaves are green and deciduous. The plant is used as a fruit crop and a decorative element in the landscape, and also serves as an effective pollinator for other hazelnut varieties.
The fruits are large, heart-shaped with a pointed apex and a wide base. The shell is brown, thick, easily crackable, and the kernel has a sweet taste. The harvest matures late, in late September or October.
The variety is characterized by high winter hardiness down to -20...-25°C and resistance to major hazelnut diseases, including bacteriosis. Due to late flowering, the plant often avoids recurrent spring frosts. To obtain a yield, the presence of pollinator varieties in the orchard is required.
