The variety is open-pollinated (not a hybrid) and suitable for organic farming. The plant is characterized as vigorous, with a short stem and a regular shape of the wrapper leaves.
The heads are distinguished by a mild-sweet taste and a juicy, crispy texture of the leaves. The variety is considered reliable for cultivation and, under proper conditions, maintains freshness until January–February.
The cabbage is intended for fresh consumption, including use in salads, as well as for long-term storage during the winter period.
