Japanese Box is a compact, evergreen shrub renowned for its dense foliage, naturally rounded habit and exceptional versatility in the landscape. A favourite for formal gardens, this hardy shrub responds well to clipping, making it ideal for low hedging, topiary, borders and feature planting. Its attractive glossy green foliage provides year-round structure and colour, while its slow to moderate growth and low-maintenance nature make it one of the most popular hedging plants for Australian gardens.

Small, rounded, glossy deep green leaves form a dense evergreen canopy, providing year-round colour and creating a neat, formal appearance.

Fruit

Small capsule-like fruits may develop after flowering but are generally insignificant and rarely noticed.

Notes

Japanese Box has long been regarded as one of the finest plants for formal hedging and topiary due to its dense foliage and excellent response to pruning. It is slower growing than many screening shrubs, allowing it to maintain a neat appearance with less frequent trimming. Its adaptability and timeless appeal make it suitable for both traditional and contemporary garden designs.
