The hybrid is characterized by a growing period of 125–130 days after transplanting. The plant has an upright growth habit, a developed root system, and a high stump, which facilitates aeration. The broad leaves are covered with a pronounced waxy bloom, helping to suppress weed growth.
The round-headed cabbages have a dense internal structure and reach a weight of 2.5–4.5 kg. The hybrid is undemanding to growing conditions and soils with low fertility. The storage period of the heads is possible until mid-June.
