Description

The green gem boxwood is a woody, broadleaf, evergreen shrub in the Buxaceae (boxwood) family. It is a hybrid cultivar of Buxus microphylla ‘Koreana’ crossed with Buxus sempervirens that was developed in Canada at Sheridan Nurseries. It is noted for its dwarf, dense, globular shape and winter hardiness. 

It grows best in well-drained soil in full sun to part shade. It is noted for requiring little pruning and its small leaves allow it to take shearing well though never prune before the last spring frost date or tender new growth can suffer damage. Location and maintenance of this plant can have an effect on its health. It prefers natural to slightly acidic or basic soil.  Its glossy, dark-green leaves hold their color well in winter; however, winter winds can cause dehydration and bronzing. Protect it by placing it in a location where these conditions are limited. Remove any accumulated snow to protect the branches. Limit cultivation around the shallow roots as it can damage the plant. Propagate by stem cuttings.

Its compact size of 2 to 3 feet high and wide makes the green gem boxwood a great choice for tight spaces, along narrow pathways, a low hedge, or beside a patio. The dark glossy leaves provide good winter interest and the plant is rabbit and deer resistant.

Insects, Diseases, and Other Plant Problems: Moderately resistant to boxwood blight. Poorly drained soils may cause root rot. Susceptible to boxwood leaf miner, boxwood psyllid, and boxwood mites. In the deep south, nematodes are a concern.
