The shrub reaches a height of 1 to 2 meters. It is distinguished by increased stem strength, thanks to which the inflorescences are held in an upright position. Flowering occurs on current year's shoots.
Mophead-type inflorescences have a spherical, flattened shape. The color of the flowers changes throughout the season: upon blooming they are lime-green, then the fertile flowers acquire a raspberry shade, and the sterile ones lighten to alabaster-white, returning to greenish tones by the end of the season.
The plant possesses high winter hardiness, withstanding frosts down to -30°C. It is used in landscape design for creating borders, mass plantings, specimen plantings, and also as a cut flower crop.
