Variety description
10 August 2026
The plant is a deciduous shrub with a dense rounded crown, reaching a height of 100–160 cm (sometimes up to 200 cm) with a width of 120–150 cm. The leaves are dark green, glossy, oval-shaped with a serrated edge. The shoots are strong and vertically directed.
Large spherical inflorescences 15–30 cm in diameter consist of pure white flowers, in the center of which a pink or blue hue may appear depending on the soil pH level. Flowering lasts from June to October, primarily on last year's shoots.
The variety is characterized by high resistance to diseases and pests. Winter hardiness is estimated at -18°C…-20°C; however, in regions with cold winters, covering is required to preserve flower buds.
