The variety forms heads of cubic, round, or slightly flattened shape with a mass of about 3.5 kg. The leaves are dark green, covered with a moderate to sparse waxy bloom. A distinctive morphological feature is the short core, which contributes to the plants' resistance to lodging.
The plant possesses good resistance to diseases and head cracking. For cultivation, fertile, humus-rich soils and sunny sites are recommended. Planting is carried out using the transplanting method, setting the plants in the ground from mid-May to mid-June with a spacing pattern from 40×50 cm to 60×70 cm.
