B. microphylla var. koreana X B. sempervirens 'Green Gem'
A great little hybrid Boxwood that requires very little trimming / pruning to maintain a perfect little round ball of tight, dark green foliage. Has shown to hold excellent green color through the winter with excellent hardiness as well. A slow grower that only reaches a mature size of about 2' x 2'. Makes a great choice for foreground plantings, as well as for short, low growing, formal hedge.

5 - 9 ( if unsure of your zone, please use zone finder below - or check out our Hardiness Zone Map & Information Page )
Full to partial sun - will even do very well in partial shade areas.
Average. Slightly cool & moist - fertile. Mulching recommended.
--Foliage Color & Texture:
Evergreen broadleaf - very typical of most B. microphylla varieties - small, oval shaped. Good dark green mature foliage - newer foliage growth slightly brighter green. Good density.
--Flower, Cone, Or Berry Facts:
Flowers - very small, rather inconspicuous, creamy yellow flowers develop in small clusters in April - May, and are actually quite fragrant for the brief time that they are present. Will attract bees while in bloom.
--Diseases / Insects:
Among the more prevalent problems one might be confronted with when growing
Boxwood would be: Canker, root rot, boxwood leaf miner, boxwood webworm, nematodes, and boxwood mites. Most all of these pests / problems are much more commonly seen on Buxus sempervirens cultivars - other variations / hybrids seem to show much more resistance to these problems. Root rot ( Phytopthora ) can be a problem in inadequately
drained soils, and is usually indicated by a lighter "off color" to the foliage. Annual treatment / inspection is strongly recommended during the early growing season in order to monitor any possible problems, and as a preventative action.
A spacing of about 20" apart is recommended for most typical low growing hedge applications.
--Deer Resistance Rating: Lowest Resistance [ 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 ] Highest Resistance
--Fertilization / Feeding:
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
