Inflorescences consist of large double sterile flowers on long pedicels, which gives them the shape of a firework. Primary petal color is white; fertile flowers in the center can change color to pink or blue depending on soil pH, and toward the end of flowering, the inflorescences turn green.
The plant forms a bush 0.8 to 1.6 m tall with strong shoots and dark green glossy leaves. The variety is distinguished by high disease resistance and belongs to hardiness zone 6, requiring cover in regions with cold winters.
The variety is suitable for landscape design, container gardening, and cut flowers. It belongs to the Hovaria series and is capable of setting flower buds on both previous year's and current year's shoots.
