Variety description
10 August 2026
The variety is a hybrid of Paulownia elongata × Paulownia fortunei, obtained via micropropagation. The plant's wood is characterized as light, durable, and resistant to deformation and cracking, making it suitable for processing and biomass production.
In favorable climatic conditions of southern European regions, the variety demonstrates rapid growth, reaching 15–20 meters in height and 25–30 cm in trunk diameter within three years. Frost resistance is estimated in the range from -25 °C to +45 °C; however, in Central European conditions, growth rates may be lower and seedling mortality higher.
The plant possesses high adaptability to various soil types. Being a sterile hybrid, this variety does not exhibit invasiveness, as its seeds are not viable.
