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


Franklin’s Gem Korean Boxwood is the perfect dwarf boxwood for colder areas in particular. It has perfect tiny leaves and naturally grows into a neat mound that is always glossy green and healthy, from the heat of summer to the cold of winter. It is perfectly hardy throughout zone 5 and it will even survive colder areas with just a little browning, yet it is also happy to grow even in the heat of Florida or California. Plus, it will grow in sun or moderate shade, meaning you can plant it almost anywhere in your garden where you need an accent plant to contrast with the more irregular growth of your other plants. Use Franklin’s Gem Boxwood in pots and planters – it is small enough to look perfect for many years. Plant a low border or hedge that will need only occasional trimming to look neat. Group them among the larger shrubs in the foundation planting around your home. Wherever you use this plant you will love the fact that it is always, neat, always green and glossy, always healthy, and needs no clipping to stay that way.

The perfect garden is a balance between order and chaos, and getting that balance right is the sign of a good gardener. The secret is to use neat, dense plants as accents to the more random growth of most garden plants – and when it comes to neat and dense, boxwood is a great choice. At the Tree Center we carry a wide range of boxwoods for lots of different needs, from the tall American Boxwood for tall hedges and specimens to the English Boxwood for low hedges and the Wintergreen Boxwood for clipped balls.

Growing Franklin’s Gem Korean Boxwood Shrubs

Franklin’s Gem Boxwood fits right in as our smallest, most compact boxwood, which is also incredibly winter hardy. If you love the neat form of boxwood, but find clipping a chore, then Franklin’s Gem is the boxwood for you. It is so neat, with tiny leaves and a perfect rounded form, that it really needs no clipping at all to be the perfect addition to your garden. Plant a pair in pots to frame your front door. Add several to the foundation planting around your home as accents and groups. Create a miniature hedge to edge a small bed by planting a row of them 18 inches apart. Wherever you use it you can be sure of a neat, pest-free plant that will be attractive and green in both cold and hot weather.

Planting Location

Plant your Franklin’s Gem Boxwood in any location, from full sun to moderate shade, in most kinds of soil. For best growth add some organic material when planting and as mulch each spring. Water your plants well during the first years and during hot, dry weather in summer. Especially if you clip regularly, use a fertilizer for evergreen plants and hedges each spring. An annual clipping at the end of winter will keep your plants extra neat, but Franklin’s Gem Boxwood is so dense it really doesn’t even need to be clipped at all.

History and Origins of the Franklin’s Gem Korean Boxwood

The Korean boxwood, Buxus sinica, which was previously called ‘microphylla’ or ‘koreana’, is a native of China and Korea. It has been grown in Korean, Japanese and Chinese gardens for centuries, loved for its compact form, with small leaves and dense growth easily clipped into various forms. It quickly became popular in the Northeast of the USA when gardeners there discovered that the English boxwood (Buxus sempervirens) was not very hardy and became brown and unsightly during the winter months anywhere colder than zone 6. However the Korean boxwood was hardier, soon becoming very popular for that reason, and nurseries found even hardier forms over time, so that with careful selection it is possible to grow boxwood throughout zone 5 with plants that remain a healthy green color all winter. Korean boxwood is also hardier and usually smaller than the Japanese boxwood (Buxus microphylla var. japonica).

The Brandywine Valley is known for its grand gardens, and many of the plants in those gardens came from J. Franklin Styer’s Nursery in Glen Mills, Pennsylvania. The nursery was founded in 1890 to supply the gardens of the wealthy properties in the area, and it was Jacob Styler’s son, Franklin, who in the 1960’s received a package of seedling boxwoods from Japan. Like all seedlings, each one was different and one in particular caught his eye. It had very small leaves and a dense, compact form that needed almost no clipping to remain neat and rounded. Not only did it remain green and glossy at the height of summer, it was also very winter-hardy, and turned a rich olive-green in winter, without any browning. It was such a gem in the garden that it soon became just that – ‘Franklin’s Gem’.

Buying Franklin’s Gem Boxwoods at The Tree Center

This special form of Korean boxwood cannot be grown from seed but must be reproduced from stem pieces skillfully rooted by expert gardeners. Our plants are exact copies of Franklin Styler’s original plant, grown form rooted pieces. You should always try to avoid cheaper plants simply labeled as ‘dwarf boxwood’, because they could be almost anything and are certainly not this very special and carefully chosen plant. We are thrilled to be able to offer you this very special form of boxwood, but we know that our supplies will quickly run out, because this plant is so popular, and rarely available. So order now for those doorway pots, or for that planting you have always wanted, and avoid the disappointment of the ‘sold out’ sign.
