Variety description

10 August 2026

The variety is late-ripening, the period from sowing to harvest takes 120–150 days. The plant has an upright growth habit, dark green leaves with a bluish tint and a waxy coating, and forms long, wide, and thick white pseudostems.

Due to its high cold tolerance, the variety is suitable for winter cultivation and can be left in the field during the cold period. In terms of quality characteristics, it is valued for its delicate taste.

The variety is an open-pollinated population, intended for fresh use, canning, and freezing. The name often denotes a type of leek classified by leaf color and ripening time and may be used for a group of similar varieties.
