The variety is an upright shrub with a height of 80–130 cm. Inflorescences in the form of flat corymbs consist of small fertile flowers in the center and a ring of larger sterile flowers on the periphery, sometimes having a double row of petals. Leaves are dark green, oval, with a serrated edge, turning orange-red tones in autumn.
Flowering occurs from June to September. The variety is moderately winter-hardy, requiring covering, as flower buds are set on the previous year's shoots. It possesses resistance to powdery mildew and strong shoots resistant to lodging. Used in group plantings, as a specimen plant, and for growing in containers.
