Variety description

10 August 2026

Plant variety type is red oakleaf lettuce. The medium-sized plant is characterized by an upright growth habit. The leaves have an intense dark red color, which is maintained even under low light intensity.

The variety is intended for professional use during the autumn, winter, and spring periods, including in heated greenhouses and hydroponic systems. It is often used in multi-colored 'trio-mixes'.

The variety possesses a high growth rate and rapid head filling. It is resistant to downy mildew (strains Bl:29-41EU), lettuce aphid (Nr:0), tomato bushy stunt virus (TBSV), as well as bolting and leaf tip burn.
