Variety description

10 August 2026

The variety belongs to the Lollo Rossa group and is a plant with a deep red color and strongly ruffled leaves. In scientific literature, it is distinguished as a mutant form possessing three genes that determine a high intensity of anthocyanin accumulation compared to related varieties.

The period from sowing to marketable maturity is from 45 to 65 days. The plant forms medium-sized heads. The variety is frequently mentioned in comparative genetic studies dedicated to the analysis of pigmentation and the influence of external factors on the concentration of anthocyanins and chlorophyll in leaves.
