Green Mountain Boxwood | Buxus x 'Green Mountain' | Elegant Shrub for Borders
Green Mountain Boxwood 6-10" (Buxus microphylla var. japonica) is a hybrid with parent cultivars of B. sempervirens 'Suffruticosa' and B. sinica var. insularis. It was developed to have higher cold hardiness and a more upright structure. There are now over 150 species and cultivars of boxwoods known to date.
This shrub can grow to 6.5 ft in height at maturity. However this particular cultivar is slow growing and will reach only 3 ft in height over the first decade of growth. Its short stature makes it an ideal walkway border or foundation plant sitting below the bottom of household windows.

Dark, vivid green in color, the foliage of the Green Mountain Boxwood 6-10" is robust and evergreen. When you look closely at the leaves of this slow-growing shrub, you see that the midline of each leaf is covered in a white pubescence. As with most boxwoods, the stems of this shrub are square, and this particular individual possesses winged attributes.
Tiny, petal-less flowers of creamy greenish white emerge in the spring but are not showy or notable from an ornamental sense. While the flowers of this shrub are not obvious, they produce a pleasant aroma that is noticeable when in bloom.
Landscape Uses | How to Maintain Green Mountain Boxwood
This shrub prefers moist, heavily mulched, cool soils that are well-drained, and it tolerates a range of soil acidity. It is a very drought-tolerant shrub but is prone to root rot in soils that are not well-drained. While it is resistant to deer, rabbits, and nematodes, boxwood mites and leaf miners will take advantage of stressed plants.
Green Mountain Boxwood grows well in dappled shade conditions. It will also grow in full shade, but it will elongate and produce sparser foliage. Full sun conditions can be too intense for this shrub and may result in the foliage turning a reddish tone. Plant this shrub in an area that is sheltered from the wind.

How To Grow
How to Grow and Care for Bare Root Shrubs
Bare root shrubs are a budget-friendly and efficient way to plant during the cooler months when they’re dormant. Before planting, soak the roots in water for 3–6 hours to rehydrate them. Choose a site with the appropriate light exposure for the species—most flowering shrubs prefer full to partial sun. Dig a hole wide enough to spread out the roots and deep enough so the crown (where the roots meet the stems) sits level with the soil surface.
Mound a bit of soil at the bottom of the hole, spread the roots over it, and backfill with native soil while gently firming it to remove air pockets. Water deeply after planting to settle the roots. Keep the soil moist but not soggy during the first growing season to encourage healthy establishment.
Mulch around the base (not touching the stems) to retain moisture and suppress weeds. Prune lightly to remove any broken branches and to shape after the first flush of growth. With minimal care, bare root shrubs will leaf out beautifully and grow into reliable, long-term landscape anchors.
