Variety description
10 August 2026
The variety is a compact shrub with sturdy stems that exceed the resistance of some other commercial blue varieties. The plant forms large, rounded mophead-type inflorescences. As the flowers age, the sepals retain a saturated hue for a long time, exhibiting resistance to browning and scorching.
The intensity of the blue color of the inflorescences is determined by the soil pH level and the presence of aluminum; an acidic environment is required to achieve a bright color. The variety is suitable for ornamental use both in open field and as a container crop due to its ability to maintain shrub shape.
