Ilex crenata (Japanese Holly)
Ilex crenata, commonly known as Japanese Holly, is a refined evergreen shrub widely used as a modern alternative to traditional box hedging. With its small, glossy leaves and naturally dense growth habit, it delivers the same formal look as Buxus without the susceptibility to box blight.
Highly valued in contemporary and classic garden design, Ilex crenata is ideal for low hedges, structured borders, topiary, and cloud-pruned forms. Its clean foliage and excellent response to pruning make it a favourite among landscapers and designers.
Key Features
- Excellent box hedge alternative – no box blight issues
- Fine, glossy foliage – refined and formal appearance
- Evergreen – year-round structure and colour
- Responds well to pruning – ideal for topiary and shaping
- Low maintenance once established
Size & Growth Habit
Ilex crenata typically grows to 2–3 metres in height if left unpruned, with a similar spread. It can easily be maintained at lower heights, making it perfect for formal hedging and border planting.
Growth is moderate and compact, allowing for precise shaping and a tidy finish throughout the year.
Ideal Uses
- Formal hedging and edging
- Box hedge replacement
- Topiary and cloud pruning
- Garden borders and pathways
- Courtyards and contemporary landscapes
Growing Conditions
- Sun: Full sun to part shade
- Soil: Well-drained, slightly acidic soil preferred
- Water: Moderate; regular watering during establishment
- Frost: Tolerates light to moderate frost
Maintenance & Care
Ilex crenata is easy to maintain and benefits from light, regular pruning to maintain shape. Feeding with a slow-release fertiliser formulated for acid-loving plants will promote healthy, vibrant growth.
Unlike traditional box hedging, Ilex crenata is not affected by box blight, making it a more reliable long-term choice for structured gardens.
Planting Guide
For hedging, space plants approximately 40–60cm apart, depending on pot size and desired hedge density. Closer spacing will result in faster establishment of a continuous hedge line.
