The tree is characterized by its compact size, reaching 6–9 meters in height, which is about 2/3 the size of other varieties. Regular pruning is required to maintain productivity. Fruiting occurs primarily on lateral buds with an intensity of 65% to 90%.
The variety is mid-season, with harvest taking place from late September to early October. The fruits have a thin or semi-thin shell that is easily separated from the kernel. Kernel yield is 47–48%. For cross-pollination, planting together with Franquette or Bilecik varieties is recommended.
The plant possesses resistance to a number of bacterial and fungal diseases. Due to late flowering, the variety effectively avoids damage from spring frosts. It requires about 400–600 chilling hours, although fruit quality may decrease in hot climate conditions.
