‘Green Mountain’ is a cold-hardy rounded conical shaped hybrid boxwood. It is often referred to as being in the “Green Series” of boxwood (see ‘Green Velvet’ for more information). ‘Green Mountain’ will bronze slightly in winter especially when exposed to direct sunlight but bronzing will quickly fade as new spring foliage begins to emerge. Deer resistant.

Prune ‘Green Mountain’ lightly in late winter or early spring to maintain desired habit. Use hand pruners or shears. ‘Green Mountain’ is often sheared in a tight pyramid or conical shape to distinguish it from other plants in the “Green Series”; however, when left unpruned, it will develop a more rounded conical habit. Thinning is not necessary but, as with any boxwood, will help increase airflow and sunlight penetration into the interior of the plant.
‘Green Mountain’ is somewhat susceptible to boxwood leafminer and shows variable results in tolerance and susceptibility to boxwood blight. It has few other pest or disease issues when planted and cared for properly.
Comments: This is another of the cold-hardy boxwood from Sheridan Nursery in Canada. Some gardeners believe annual light prunings are necessary on this cultivar to improve its rigidity as an upright plant or the plant may open up with snow. It grows with relative vigor until it is about 15 years old then slows down.
Uses: Medium specimen, medium hedge, low hedge, foundation plant, containers
Substitutes: ‘John Baldwin’, ‘Dee Runk’, ‘Fastigiata’
