Slow-growing evergreen native shrub with small dark glossy leaves, exceptional density, and unmatched fineness of clipping detail. The classic European formal-garden topiary, parterre, and low-hedge species.

| RHS hardiness rating | H6 | −20 °C to −15 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 6–8 | −18 °C to −1 °C | Plant tolerates down to this zone |
| Australian (ANBG) zone | Zone 2–5 | −10 °C to 10 °C | Plant tolerates down to this zone |
Growing notes
- Slow-growing and exceptionally dense — the only realistic species for fine-detail topiary, knot-garden parterres, and tightly clipped low hedges
- Cuttings and trimmings have provided premium pale fine-grained turning wood (the original wood of boxwood combs, ruler scales, and woodwind instrument flutes) for centuries — hence the name
- WARNING: Box blight (Cylindrocladium buxicola / Volutella) and box tree caterpillar (Cydalima perspectalis) are currently devastating box hedges across Europe — manage proactively, consider resistant alternatives (Ilex crenata, Pittosporum tobira) in heavily affected regions
- Shade tolerant — succeeds under tree canopy where most evergreens fail
Pet caution: Common box is listed as potentially harmful to cats and/or dogs. Keep pets from grazing on it, and contact a vet if you suspect your animal has eaten some.
