The variety is a compact shrub with a height and width of 0.75–1.2 m. The plant is characterized by high winter hardiness (USDA zones 3–9) and good adaptability to different soil types, provided there is drainage. An important feature is the strength of the stems, capable of holding large inflorescences in an upright position without lodging.
The inflorescences have a spherical shape. During the flowering process, the color changes: the initially intense lime-green color transitions to a soft greenish-white, and towards the end of the season, it returns to greenish tones. The variety is suitable for use in landscaping, group plantings, borders, as well as for growing in containers, cutting, and drying.
