Variety description

10 August 2026

The plant forms a transitional type bush 180–200 cm tall with narrow leaves of a deep green color. The variety is distinguished by early flowering, which begins in the second half of July, and high ornamental value. The growing season often ends before the onset of frost.

The tubers have a dark yellow color, branch heavily, and resemble fused groups in shape. Due to their complex shape, the tubers are considered less suitable for culinary use. The variety is a good honey plant.

Tuber yield reaches about 48 t/ha, while the above-ground biomass is approximately 15 t/ha of fresh weight. The variety is adapted to the climatic conditions of the Czech Republic.
