Variety description

10 August 2026

The variety belongs to the group of winter butterhead lettuces. The plant reaches a height of approximately 20 cm and forms large, dense heads. The leaves have a rounded shape, a light green color with brown or reddish spots, and are characterized by a tender and crispy texture.

The variety possesses excellent winter hardiness and is capable of withstanding frosts down to -10°C, which allows it to be grown as a winter or early spring crop. Seeds are sown in August–September to obtain a harvest from late winter until May. When planting, it is recommended to maintain a distance of approximately 30 cm between plants.
