How to Grow Green Mountain Boxwood

The green mountain boxwood is considered by many gardeners to be the all-around ideal shrub for most residential gardens. It is also a conservative but pleasant shrub for commercial areas, too! There are plenty of boxwoods out there and if you’re on the hunt for a shrub then you’re probably wondering what the difference is between all of the boxwoods in the gardening world. For most varieties, the difference can be seen in one or several characteristics, such as the plant’s size, rate and style of growth, longevity, “fullness,” and ease of maintenance. If you have stumbled upon the green mountain boxwood, then you are probably giving this plant some consideration and wondering if it may be right for your yard. In order to find your answer, keep reading to learn what you could expect this plant to look like once it matures, what kind of environment it can grow in, and how it should be properly planted and maintained.


The green mountain boxwood is the result of crossing two popular Asian and English boxwood varieties. What occurred with this crossing is actually a mixture of the best bits that the Asian and English boxwood varieties had to offer, which means that the green mountain boxwood is one of the most preferred shrubs in gardening communities. The average green mountain shrub grows about three feet tall and around three feet wide. If the plant is in an environment where it is truly able to thrive—or if it is well taken care of by its owner—then it may grow as tall as five or six feet with a three foot spread.

This is a great boxwood variety because it is so versatile and convenient. It produces small, oval-shaped evergreen broadleaf that is light green while the plant is young and then it darkens as the shrub reaches maturity. The growth pattern of this type of boxwood is actually quite impressive, as it naturally grows into the classical tear-drop or pyramid shape; however the foliage is so thick and tightly packed that it can be pruned or trimmed into a variety of topiary shapes! The foliage of this shrub isn’t just pretty in the growth season, but it also maintains beautiful color and thickness during the winter season—a trait that not many plants have!

Boxwoods are naturally versatile and the green mountain variety is definitely a great choice for any yard, especially if the idea of using a shrub as a makeshift privacy wall is attractive to you. The boxwood species is very well suited to create a hedge that, with a mature height around four feet, can allow for a bit more privacy in your garden or shield your windows from the view of neighbors or passersby.

Growing Conditions

The green mountain boxwood is very tolerant of less than ideal conditions. This species typically does well in USDA zones four through nine and is one of the more hardy boxwoods when it comes to both cold weather as well as drought. This is a very flexible shrub as far as its location goes. Whereas with most plants you would have to spend a lot of time observing your garden in order to locate the spot with the ideal amount of sunlight exposure, this variety of boxwood actually does fine in anything from partial shade to full sun. That means that it can grow in a spot that receives anything but complete and total shade. How’s that for convenient? Seeing as most people want a boxwood plant either to create privacy or to show off as a topiary bush, meeting sunlight requirements usually isn’t a problem. There is one thing that you really should give extra consideration to when choosing a location for this shrub, however, and that is drainage. “Drainage” is the term used to describe how well the soil in a particular location allows water to make its way through the dirt. An ideal location would be able to collect water for a long enough period of time that the shrub can absorb it without holding the moisture too long. The spots in your yard that are the last to see a rainwater puddle go are probably not good spots, as these areas allow water to collect and could rot the roots of your shrub—a condition that boxwoods are especially susceptible to.

Planting and Care

If you aren’t very experienced with gardening, or if you simply don’t have the time/desire to dedicate to a fussy, needy plant, then the green mountain boxwood is definitely a good variety to consider. To plant this shrub, all you need to do is dig a hole that is about two times the size of the plant’s roots. Sit the roots into the hole so that ground level is only about an inch above the part where the shrub’s roots begin. Fill in the hole with soil, being sure to pack it in firmly so that the shrub doesn’t get knocked over or otherwise uprooted. Water the area immediately after planting and about once a week for the first month. Continue to water the shrub during hot or dry periods during the first year after planting. If you plant more than one green mountain boxwood shrub then be sure to space them out by about five feet. Even with this much distance between the plants, they will still grow wide enough upon maturity to touch one another, creating a privacy hedge. If you want more space between them then you can simply plant them further apart or prune them as needed.
