The shrub has a dense compact shape, reaching 80–90 cm in height and width at maturity. Foliage is dark green with a characteristic bronze tint. Sturdy stems support large dome-shaped inflorescences well, maintaining stability even during heavy rains.

Flowering lasts from July to September. The flowers have a pink hue, the intensity of which may depend on soil acidity. The plant belongs to USDA winter hardiness zone 3a, withstanding frosts down to –34.5 °C.

The variety prefers moist, well-drained soils and sunny or semi-shaded areas. It is used as a solitaire plant, for forming borders, hedges, container cultivation, as well as for cut flowers.
