Variety description

10 August 2026

The variety belongs to the Salanova butterhead multi-leaf lettuce type, which is characterized by the separation into many individual baby-sized leaves upon a single cut at the base. The plant forms a compact bright green head and is distinguished by rapid head filling.

The crop possesses high resistance to downy mildew Bremia lactucae (races Bl:29-37, 39-41EU). The variety is suitable for cultivation in hydroponics and other methods, and is recommended for organic production. It is intended for fresh consumption as ready-to-use portioned produce.
