Variety description

10 August 2026

The plant is a dwarf, densely branched shrub 90–120 cm tall. A distinctive feature of the variety is the sturdy stems of purple-brown or purple-black color, contrasting with the dark green rounded foliage with serrated edges.

The mophead-type inflorescences have a pink color, which changes to blue or purple depending on soil acidity and aluminum availability. Flowering occurs from early to late summer, with inflorescences reliably held by sturdy shoots.

The variety sets flower buds on old and new wood, which ensures flowering stability. The plant is well-suited for container cultivation, creating borders, and group plantings.
