The variety belongs to the baby leaf type and matures in 35–45 days. It forms an upright rosette with firm, bright green leaves of delicate taste. The plant has the ability to bolt slowly in the summer period, which ensures long-term field stability.
The produce is distinguished by high marketability and is suitable for long-term storage and transportation. The variety possesses high resistance to powdery mildew (races Bl:16–36EU or Bl:16–37EU) and lettuce aphid (Nr:0).
The variety is universal and suitable for all-season cultivation in open field and protected cultivation, including hydroponic systems. It is intended for obtaining produce for the fresh market.
