The tree has moderate vigor and a semi-erect canopy of medium density, reaching a height of 7–20 meters. The variety is characterized by lateral bearing, where fruits are formed from lateral buds, which account for 85–90% of the total number of fruitful buds. It begins bearing fruit 3–4 years after planting.
Large, oval-shaped nuts weighing 12–16 g have a thin, easily cracked shell. The kernel percentage is 50–55%. The variety is protandrous and requires the presence of pollinator varieties for effective pollination. The ripening period occurs in late September — October.
The variety is better protected against spring frosts than many analogs due to its late emergence from dormancy. It is resistant to anthracnose, but can be susceptible to bacterial blight. The tree requires about 700 hours of chilling at temperatures below +7.5°C.
