Variety description

10 August 2026

The plant forms a compact shrub reaching a height of 1.0–1.2 meters. The inflorescences of the variety are cherry-red in color. The variety is remontant, which allows it to form inflorescences on both last year's and new shoots.

The plant is adapted to USDA hardiness zones 6–8. When temperatures drop below –18 °C, the shrub requires protection. The variety is suitable for planting in mixed borders and container cultivation, while requiring the maintenance of a constant soil moisture regime.
