Variety description

10 August 2026

The variety has a vegetation period of 65 to 80 days and reaches a height of 70 cm. The plant forms a contrasting rosette of dark green leaves and a white stem 10–12 cm long, possessing high marketability and long shelf life after harvest.

Due to its intensive waxy bloom, the variety is characterized by increased resistance to downy mildew and other fungal diseases. The crop is frost-hardy, resistant to overgrowth, and suitable for cultivation in both open field and protected cultivation throughout the entire season.
