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.

Boxwoods are everyone’s favorite when it comes to low hedges and accents around the garden. Especially in a more ‘formal’ garden, but really, also attractive in any setting, boxwoods are garden staples that bring structure and form, visually ‘taming’ the wilder and more rampant plants around them. Unfortunately, when the early settlers brought boxwoods with them to the early United Sates, they quickly discovered that the harsh climate was not to their liking. Ever since that time, American gardeners have craved hardy boxwoods, at least they did until the Sheridan Green Series was created in the cold Canadian provinces by Sheridan Nurseries.
Top spot in the Series must go to the Green Gem Boxwood, because it solves not one but two of the biggest objections to growing boxwood. It is super-hardy, surviving even up in Canada and keeping its healthy, rich-green foliage all winter long. While most other forms turn bronzy-brown and suffer die-back of the branches in zones 4 and 5, not the Green Gem Boxwood, which stays fresh and green year-round. The second great thing is that this plant needs little or no clipping to develop into an almost perfect round ball, 2 to 4 feet across and wide. Especially in a more relaxed garden, unclipped plants are perfect – dense, rich-green and neatly rounded. Of course if you wish you can clip this plant as often as you wish, to keep it a perfect sphere, and with such a neat grower, most of the work is already done for you and you just need a trim to keep the Green Gem Boxwood super-tidy.
Growing Green Gem Boxwoods
The Green Gem Boxwood grows between 2 and 4 feet tall, and it naturally stays the same across – an almost-perfect sphere. As well, this hybrid plant combines the American boxwood with the hardy Korean boxwood, producing a plant that is good looking, but also hardy like its Korean parent. This doesn’t mean the plant is only valuable in cold areas, because it is still a top choice for an easy-care spherical boxwood of medium size, all the way into zone 9, which covers almost all the country. No matter Where you live, this plant is a great boxwood choice.
Sun Exposure and Soil Conditions
The Green Gem Boxwood can be planted in almost all light conditions, from full sun to almost full shade. Avoid very dark places underneath low trees, and in hotter areas some midday and afternoon shade is appreciated, as that will keep your plants a rich, dark green. This plant grows in every soil-type, from sandy soils to clay, as long as it is not in soil that is always wet and boggy. Enriching 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. This plant has few significant pests and diseases and it is 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.
History and Origins of the Green Gem Boxwood
American boxwood, Buxus sempervirens, is, despite its name, a European plant that was originally brought to American in 1653 for the early colonial gardens. The cold climate in the north-east was not very suitable for its growth, and in the 19th century other boxwoods from Asia were imported, to find hardier substitutes. Among these was the Korean boxwood. That plant, called today Buxus sinensis var. insularis, is much more reliable in cold climates, but it is less attractive, with foliage that is not as glossy and eye-catching as the American boxwood, so there was room for improvement
More than anyone else in North America, Canadians know how to garden successfully in cold conditions, so it was natural they would take up the challenge to develop better boxwoods for America. Plant breeders at Sheridan Nurseries, in Ontario, a long-established family business, decided to tackle the problem of creating hardier boxwood plants. Starting in 1955, they took a batch of seedlings from a cross between the English and Korean boxwoods, and carefully tested them for form and hardiness. One – soon to be called ‘Green Gem’ – had a remarkably neat, rounded form that caught the breeder’s attention. It was released in 1973, and is renowned as the top choice for a natural ball-shaped boxwood, especially in cold climates. Other boxwoods in the series, such as Green Mountain, are also among the best boxwoods for colder climates.
