Variety description

10 August 2026

The trees of this variety have a compact size, and the crown tends to spread laterally. The variety is early-maturing, ripening 10–14 days earlier than the «Barcelona» variety. Upon ripening, the nuts fall out of the husk on their own.

The nuts are small, with an average weight of about 2.3 g, and a kernel weight of 1.1 g. The variety has complete resistance to Eastern Filbert Blight and high resistance to the big bud mite. The kernels blanch well.

The variety is self-incompatible and requires the presence of pollinator trees, such as «Sacajawea», «York», «Gamma», «Dorris», «Wepster» or «Jefferson».
