10 August 2026
The tree is medium-sized, with an upright crown and a branch angle of less than 45 degrees, reaching a height of 8–10 meters. The variety is early-bearing, characterized by a lateral fruiting habit; female flowers can appear in the second year after grafting.
Nuts are round, large, weighing 15–20 g, and have a smooth shell of medium thickness. The kernel is light cream in color with a yield of up to 55%. The variety is protandrous, with fruit ripening occurring in September.
The variety is sensitive to severe frosts and is better adapted to regions with a mild climate. Late flowering reduces the risk of damage by spring frosts, and high tolerance to diseases allows its use in commercial and home gardening.
