How are the heights measured?
All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.
What is a gallon container?
Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.
How does the delivery process work?
All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!
Why are some states excluded from shipping?
The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.
About Me

The Green Mountain Boxwood is a premium boxwood selection that is ideal for creating medium-sized hedges and upright specimens. It is much more cold-resistant than ordinary American boxwood, so if you live in a colder area, this is the ideal plant for those decorative cones and pyramids that bring such a classic look to any garden. Because it is a hybrid it is a tough, reliable plant that will grow well in a wide range of conditions – both cold and hot. It thrives in almost all light levels, from full sun to full shade, and its rich-green and glossy foliage is attractive all year round. It is ideal fom making hedges up to 5 feet tall, or for trimmed specimens in a wide range of shapes. In a lower-maintenance garden it can be grown with little or no clipping, as a dense, billowing upright shrub for evergreen structure and permanence. Around your home, or in garden beds, it will give your garden that air of maturity and stability that creates a calming and attractive atmosphere.
- Hardy boxwood variety for colder areas
- Grows naturally into an upright, conical shape
- The top choice for taller clipped cones and pyramids
- Perfect for a medium-sized hedge
- Evergreen and attractive all year round
The Green Mountain Boxwood will grow in almost any garden soil that is not constantly wet. This tough plant will grow well with minimal care, but it will thrive on a simple watering and fertilizing program. It can be left untrimmed and it will still be neat and compact, or with clipping it can be turned into a beautiful hedge or striking formal specimen for your garden. It is free of major pests or diseases, especially when clipped, and it is resistant to moderate drought once established, as well as to deer. Rather than settling for generic ‘boxwood’, choose a variety specially raised for hardiness and upright form.
- Plant Hardiness Zones 4-9
- Mature Width 2-3
- Mature Height 3-5
- Sun Needs Full Sun, Partial Sun, Shade
Boxwoods are a mainstay of gardens, particularly among gardeners who like to see formal clipped shapes, but also with those who look for stable shapes in their gardens. Having permanent structure is important in any garden, as it forms the stable background to the daily changes in flowering plants and trees.
Many boxwoods are low growing, and suitable for low hedges or clipping into balls, but sometimes what we want is something taller, for a taller hedge, or for creating large pyramids and cones. If you are fortunate enough to live in a milder area, then the American boxwood will be perfect for that job, but that plant is really only hardy to zone 5, so if you live in a colder area, finding something suitable can be a challenge. Or at least it was, before the development of the Green Mountain Boxwood.
This superb plant forms an upright shrub with a natural conical shape, reaching 5 feet tall, but staying only 2 to 3 feet wide. Best of all, this hybrid plant combines the genes of the American Boxwood with the hardy Korean Boxwood, producing a plant with all the good-looks of the American one, but with the hardiness of its Korean cousin. If you live in warmer areas, this plant is still an excellent choice, because it has a natural conical form, and it is tough and reliable. If you want a medium-sized hedge, or clipped cones and pyramids, this is a great choice wherever you live.
The Green Mountain Boxwood can be planted in a row to form a hedge anything between 2 and 5 feet tall – perfect for sub-dividing your garden into garden ‘rooms’ for multiple functions. As well, it clips easily into upright cones or pyramids, bringing height and strength to the arrangement of your garden. It can also be used more informally, with little or no clipping, to bring a strong upright form to your background shrubs, or the foundation planting around your home. Only a few gardeners think to plant boxwood as a natural, unclipped shrub, but it works well in that form, creating beautiful billowing shapes in permanent rich greens all year round.
Origins of the Green Mountain Boxwood
American boxwood (Buxus sempervirens) is, despite its name, a British and European plant that was brought to American in 1653 for the early colonial gardens. The colder climate in some parts of the country proved too much for it, and it was only in the 19th century that other boxwoods from Asia were introduced, including the Korean boxwood. That plant (Buxus sinensis var. insularis) is much more reliable in cold climates, and is very popular, but its foliage is not quite as glossy and attractive as the American boxwood.
If anyone in North America understands gardening in cold conditions, it must be the Canadians, and plant breeders at Sheridan Nurseries, in Montreal, decided to tackle the problem of creating hardier boxwood plants. Starting in 1955 with a batch of seedlings from a cross between the English and Korean boxwoods, they eventually released four special hybrids. These had been carefully tested for hardiness, and one – called ‘Green Mountain’ – was notable for its size and natural upright form, as well as, of course, for its hardiness. It was released in the mid-1960s, and has become the gold standard for a taller, upright boxwood in cold climates.
Planting Your Green Mountain Boxwood
The Green Mountain Boxwood can be planted in almost all light conditions, from full sun to full shade. Avoid very dark places underneath low trees, but in all other garden locations this plant will thrive. It grows well in almost any type of soil, from sand to clay, as long as it is not constantly wet.
Improving the soil with organic material before planting will get your shrubs off to a great start, and a regular program of watering and fertilizing will give you maximum growth and perfect health. For a hedge, put plants 12 to 18 inches apart, in a row. Don’t plant too close to fences or walls – allow at least 12 inches between the hedge and the fence.
This plant has few significant pests and diseases and it usually avoided even by deer. Trimming can be done throughout the growing season, from spring to early fall, but avoid clipping in winter, especially if you live in a cold area.
Quality of Our Green Mountain Boxwoods
It is important, if you are planting boxwoods, to be sure you have the plant that is best for your purpose, and cheap seedling trees, that have not been selected or tested for hardiness, will simply not give you the results you need, and be a great disappointment. Our plants are exact duplicates of that original tough plant, and they are grown from selected stem pieces that are carefully rooted and grown under controlled conditions to be the best possible specimens of this valuable plant.
