Variety description
10 August 2026
The plant is a bushy, dense, upright shrub with good branching. The leaves have a heart shape, serrated edges, gray-green coloration, and a characteristic aroma. The flowers are large, blue-violet in color, and gathered into spike-shaped inflorescences.
The variety flowers for a long period: from May until the end of summer or early autumn. It possesses strong, stable stems and high drought tolerance after rooting, and is adapted to USDA hardiness zones 3–8. The variety is a sterile hybrid, does not self-seed, and is propagated by division of the bush.
