Variety description

10 August 2026

The hybrid forms an upright rosette of elliptical, blistered, medium-sized leaves with wavy edges and a waxy bloom. Round-flat heads have a medium-bumpy surface and a milk-white color; their structure is characterized as tender and dense.

The plant is noted for high resistance to leaf tip burn and adverse weather conditions. The self-covering ability protects inflorescences from yellowing and exposure to sunlight. Yield is approximately 5.5 kg per square meter.

The produce is intended for sale on the fresh market, home cooking, freezing, and canning. The hybrid is recommended for cultivation in the open field, primarily during the autumn period.
