10 August 2026
The variety belongs to the Butterhead lettuce type. The plant forms medium-sized heads with a rounded base, light to medium green leaves, slightly pronounced blistering, and a noticeable central vein.
The plant possesses high resistance to downy mildew (Bremia lactucae, races Bl:16-25, 27, 30-32 EU) and aphid (Nasonovia ribisnigri, race Nr:0). The variety is characterized by slow bolting, which ensures production stability under various cultivation conditions.
