A new cultivar characterized by its strong stems that are dark purple-brown to purple-black in colour, its dwarf plant habit, its dark green foliage, and its mophead type inflorescences that form a flattened mound and are pink in colour (bluer in colour depending with alkaline pH and sufficient aluminium levels). It was selected as a single unique plant from amongst seedlings that were grown in a seedbed and derived from open pollination of Hydrangea macrophylla `Blaumeise`.
