Variety description

10 August 2026

The variety belongs to the group of small-flowered chrysanthemums. In the literature, it is documented as standard material for experiments dedicated to the study of photoperiodism, the influence of temperature regimes on growth, and the development of breeding methods.

The plant possesses sensitivity to environmental conditions: high temperatures in the range of 26–32 °C lead to a delay in flowering. Also noted is the variety's susceptibility to physiological damage of cuttings during their storage in low-temperature conditions.
