Variety description

10 August 2026

The hybrid is late-maturing and intended for harvesting in late autumn, winter, and early spring. The plant forms erect dark blue-green leaves and a dense blanched stem 20–22 cm long, which is easy to peel.

The variety is intended for open field cultivation and is characterized by high stress tolerance, resistance to bolting and pests, in particular to thrips. The produce has high marketability and uniformity, which facilitates preparation for sale on the fresh market.
