The variety is a compact, dense shrub 80–120 cm high with a comparable crown width. The plant forms large spherical inflorescences of double flowers arranged on three levels. Due to strong shoots, the inflorescences maintain an upright position.
Flowering continues from early summer to autumn. In acidic soils, the petals acquire a blue-violet hue, and in neutral or alkaline soils, a pink-crimson one. The variety is suitable for landscape design, cut flowers, and container cultivation. Frost resistance is down to -20°C.
The right is granted for a limited term: propagation of the variety requires a license from the rights holder.
