Variety description
10 August 2026
The shrub forms a dense upright crown ranging from 100 to 150 cm in height and approximately 100–120 cm in width. The plant possesses bright green ovate leaves.
The flowers are gathered in large, dense, spherical, snow-white inflorescences, which may acquire a pink hue or speckling by autumn. The flowering period lasts from June to September.
The variety is considered hardy with good winter hardiness; however, flower buds require protection in regions with severe winters. The plant prefers semi-shaded areas with moist, well-drained, humus-rich soils.
It is used as a specimen plant, in group plantings, and in flowering hedges; it is suitable for container cultivation and for cutting in floristry.
