Variety description

The bush reaches a height of 1–1.5 meters. The leaves are bright green in color and may acquire reddish shades by autumn. The flowers have a serrated petal edge. The variety blooms in the summer period, from the end of July to September, on shoots of the previous and current year.

The plant is thermophilic, hardiness zone 6 (-18°C to -23°C); in central regions, it requires cover. It prefers moist, fertile, well-drained soils and partial shade. It does not tolerate lime due to the risk of chlorosis development. The variety is resistant to diseases and is used in landscape design and container cultivation.
