The variety features double flowers with a creamy center. Petal color varies from pink on alkaline soils to blue on acidic soils. At the beginning of flowering, the inflorescences resemble a lacecap, but as they develop, they become fully filled, turning into a dense sphere.
The plant has a compact habit with strong, upright stems that prevent inflorescence lodging. The flowering period lasts from mid-spring to early autumn. The variety is suitable for container cultivation and as a specimen plant in gardens.
