Variety description

10 August 2026

The plant is a compact, rounded shrub with a height and width of 90–120 cm and a slow to moderate growth rate. The leaves are bright green, glossy, oval-shaped with serrated edges and increased resistance to powdery mildew. The stems are strong, upright, and support the inflorescences without staking.

Mophead-type inflorescences reach 20 cm in diameter. The flower color varies depending on soil pH: from blue in acidic environments to pink or lilac in neutral and alkaline ones. Blooming continues from summer to early autumn.

The variety belongs to USDA hardiness zones 5–9; when grown in colder regions, protection is required. Used for solitary and group plantings, creation of borders, hedges, as well as for container cultivation and cut flowers.
