The hybrid forms round-shaped heads with a short or medium internal core. The leaves are grey-green with a medium-intensity waxy bloom. The heads are characterized by a high degree of uniformity and density.
The plant possesses intermediate resistance to diseases. The recommended planting density is from 40 000 to 60 000 plants per hectare, which allows for variation in the final head size. The hybrid is suitable for organic farming.
