The variety forms round heads with a short core. The intense dark red, almost violet color corresponds to the variety name, which means "black head". The weight of a marketable head is approximately 1.5–2 kg.
The plant is intended for cultivation in open field conditions and exhibits low requirements for growing conditions. It is a variety, not a hybrid, which allows for the preservation of characteristics when propagated by seeds. The variety is versatile, suitable for early and autumn cultivation, and has limited storage life.
