Variety description

10 August 2026

The plant is an upright shrub with a well-branched structure. The inflorescences reach 40–55 cm in length, are dense, and consist of large sterile flowers. The color changes throughout the season from lemon-green-white to green-pink, then to deep pink and bright cherry.

The variety has high resistance to lodging due to sturdy stems that well support heavy inflorescences. It is resistant to wind and rain. Frost resistance is rated down to -30 °C, which corresponds to USDA zone 4.

The flowering period lasts from July to September. The intended use of the variety includes application in solitary and group landscape plantings, as well as container cultivation.
