Variety description
10 August 2026
The plant forms a large dark green rosette with a bright yellow inner part and is characterized by vigorous growth. The variety belongs to the Knox line, which ensures delayed oxidation of leaf sap after cutting and increases the shelf life of the finished product.
The variety possesses high resistance to downy mildew races 29–41EU and lettuce aphid, as well as high resistance to bolting. It is characterized by a long harvest period.
It is intended for professional cultivation in protected ground: in the winter period in unheated greenhouses, with low heating, or in tunnels. The recommended planting density is 12–14 plants per 1 m².
