Variety description
10 August 2026
The variety is characterized by high growth energy, reaching up to 6 meters in height during the first year of life. In the initial development period, the plant directs resources primarily toward height increase rather than trunk thickening. The tree has a moderately spreading crown and very large leaves, making it sensitive to strong winds.
Technical characteristics include a straight and uniform trunk, which reduces the need for pruning. The timber maturation period is 9–10 years. Frost resistance is estimated at up to -20°C. Recommended planting density varies from 400 to 660 trees per hectare, depending on growing conditions.
The plant is used as a honey plant due to the presence of attractive flowers. Specific data on resistance to phytopathologies are not provided in the materials.
