The plant belongs to the lacecap inflorescence group. Flower color varies from bright blue in acidic soils to pink in alkaline soils. The flowering period occurs during the summer months.
The variety is fully winter hardy and adapts to various types of well-drained fertile soils. It can be grown both in the sun and in partial shade; however, in open sunny areas, it requires monitoring of soil moisture.
