Variety description
10 August 2026
The variety is a hybrid of Asian boxwood species with a rounded, dense crown structure. The mature plant reaches 0.9–1.5 m in height and width. The foliage is small, glossy, changing shade from bright green on young shoots to deep emerald on mature ones.
The plant is characterized by vigorous growth and high resistance to boxwood blight (Calonectria pseudonaviculata) and box tree moth infestation. Due to dense branching, the variety maintains its shape well and is suitable for creating hedges, borders, and topiary compositions. Winter hardiness corresponds to USDA zones 5–8.
