| ID Characteristic |
| This species of boxwood is a dense, compact, evergreen shrub whose leaves often bronze in winter. ‘Compacta’ is an extremely slow-growing cultivar that may reach only 20-25 cm tall in the first 15 years. It is valued as a bonsai plant. Forming a dense evergreen mat over some years. |
| Pests |
| As of late Boxwood blight has become a major problem both in Europe and most of North America. The fungus Cylindrocladium buxicola causes leaf spots, defoliation and even extensive die-back. The disease can be spread by water splash, tools and footwear and can survive for up to six years in the soil. It thrives in moist, humid environments but is killed when exposed to temperatures in excess of 33 °C for at least a week. The disease also affects Pachysandra, Sarocococca and Buxus balearica, sinica, macowanii, microphylla, bodinieri, glomerata, harlandii, sempervirens and riparia. |

| Propagation |
| Propagate in mid-summer by taking semi-ripe cuttings from the current season's growth. Collect in the early morning using a sharp knife to cut pieces 10 - 15 cm in length. Remove all leaves from the lower third and pinch out any soft terminal growth. Dip into a number 2 rooting hormone, insert into trays or pots of cutting compost (50/50 mix of compost and sharp sand or perlite) and water well. Place in a propagator with bottom heat set at 15°C with or without mist; rooting should occur in 4 - 6 weeks. |
