10 August 2026
The plant is a medium-sized tree or bush 3–4 meters in height. The medium-sized nuts weighing 2.5–3 g have an almost perfectly round shape, brown shell with dark stripes and pronounced grooves on the sides. The white dense kernel has a caramel aftertaste, and its kernel percentage is 44–48%.
The variety is early-ripening; fruit ripening occurs in early September. The crop is high-yielding, resistant to bacterial blight, and has low susceptibility to the hazelnut bud mite. The plant is self-incompatible, therefore pollinator varieties are required, such as San Giovanni, Mortarella, Tonda Gentile Romana or Camponica.
The variety prefers fertile areas with moderate humidity and good lighting. Due to early flowering, there is a risk of damage by spring frosts.
