Variety description

10 August 2026

The variety was bred in Norway based on an ecotype from Rennebu. It belongs to the intermediate type of white clover, which provides it with better longevity and grazing tolerance compared to large-leaved varieties.

The plant is adapted to northern latitudes and is characterized by high winter hardiness. Biomass and stolon parameters depend on temperature conditions: as the temperature increases, the variety more actively increases its mass and shoot length.

The variety is used in pasture mixtures and perennial grass stands. Due to its ability to fix nitrogen, it allows for increasing productivity and forage quality without applying significant amounts of nitrogen fertilizers.
