Variety description
10 August 2026
The variety is a butter multileaf lettuce type. Thanks to Knox technology, leaves turn pink more slowly at cut sites, which extends their shelf life. When the base is cut, the head breaks into many individual leaves of the same size.
The plant forms an upright rosette with damage-resistant leaves of a sweetish taste. The variety is characterized by high resistance to bolting, downy mildew (races Bl:16–37EU), and lettuce aphid (Nr:0).
