- Description
-
‘Green Mountain’ boxwood is a woody, broadleaf, evergreen shrub or small tree in the Buxaceae family developed in Canada at Sheridan Nurseries. Buxus is the Latin name for boxwood or box tree. Originally from Europe and Asia, boxwoods are one of the oldest known garden plants, dating back to 4000 BC.
It is noted for its dense, upright, pyramidal shape that tends to fill out right to the ground. It is a slow grower and will mature to 2 to 3 feet wide and 4 to 5 feet high. It grows best in partial shade to full sun; morning sun is preferable. It will tolerate a variety of soil textures as long as they drain well.
Protect ‘Green Mountain’ boxwood from winter winds, as they can cause dehydration and bronzing. Remove any accumulated snow to protect the branches. Limit cultivation around the shallow roots as it can damage the plant. Protect the roots with a layer of mulch. Thinning plants annually through pruning will assist air circulation. Prune after the last frost.
‘Green Mountain’ boxwood can easily be shaped into a formal hedge and is sometimes seen pruned to a decorative spiral-shaped topiary. It is common in English gardens and winter gardens and is good for pollinator gardens as it attracts bees.

Insects, Diseases, and Other Plant Problems: Moderately susceptible to boxwood blight. Root rot can also be an issue in wet locations. Insects affecting boxwood include boxwood leaf miner, boxwood mite, and boxwood psyllid. Nematodes are an issue in the deep south.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common boxwood insect pests and diseases.
