The shrub has a rounded shape and grows relatively slowly. In open field cultivation, the height and width are 80–120 cm, while in container cultivation, the bush dimensions are more compact — 0.4–0.6 m. The leaves are large, broadly ovate, dark green, and young shoots may have a bronze-chocolate hue.
The inflorescences are spherical, with a diameter of up to 18–20 cm. The flowers have serrated, slightly pointed petals; the coloration varies from dark pink to red with a creamy-white center. On acidic soils, the petals acquire purple-violet tones. The plant stems are characterized by their strength.
The flowering period lasts from June to September-October. The variety belongs to the 6th hardiness zone, withstands temperatures down to -18…-23°C, and requires covering in regions with harsh winters. The plant is suitable for individual and group plantings, container cultivation, and cut flowers.
