Variety description

10 August 2026

The plant forms a vigorous bush with large dark green leaves 15–20 cm in size. Dense hemispherical inflorescences reach 20–25 cm in diameter, individual flowers are 9.5–10 cm in size.

The variety is suitable for cultivation in open field and for cut flowers. The color of the inflorescences depends on growing conditions and soil acidity, manifesting in tones from light green to pink and blue. To ensure flowering, it is required to preserve last year's shoots and cover the plant for the winter.
