Variety description

10 August 2026

The variety forms a long and well-blanched pseudo-stem. The plant is distinguished by its large size, tenderness, and pronounced aromatic properties. Due to its high resistance to cold, the crop can be left in the ground until the onset of winter.

The variety is traditional for French cuisine and is used for preparing soups and stews. It is valued for its reliability and the possibility of obtaining a harvest during the cold season.
