Variety description

10 August 2026

The tree is vigorous, fast-growing, and requires a significant feeding area. The variety is classified as early or mid-early; harvest usually falls at the end of September. The fruits are large, the kernel yield is about 59 percent, and the shell is of medium density.

The variety is better adapted to warm regions and is resistant to sunburn. Due to early bud break, there is a risk of damage by spring frosts. In the presence of excess pollen, shedding of female flowers may be observed; the variety requires pollinator trees.
