Variety description

10 August 2026

The plant reaches a height of 65–70 cm and forms spreading clumps with a large number of pseudostems and bright green hollow leaves. The variety does not form true bulbs; only the appearance of minor thickenings in the lower part is permissible.

The greens have a delicate, mild to medium-sharp taste. The variety is characterized by high frost resistance, the ability to tolerate light shading, and resistance to premature formation of flower stalks.

Intended for fresh leaf production. Suitable for perennial cultivation in one location; the optimal growing period in one bed is 3–4 years. The variety is also classified as a winter crop due to its ability to resume vegetation early in the spring.
