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.
Plant Facts & Specifications
2 - 3 ft
2 - 3 ft.
Slow ( 3" - 5" avg per yr )
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 POOPeas for use with all of evergreen species. However, either water soluble ( Miracle Gro, or equivalent ), or granular fertilizers ( Holly Tone is excellent ) are also good options. Most any granular fertilizers with a 6-12-12, or 10-10-10 ratio are also acceptable. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting.
POOPeas may be used at anytime.
Additional Features & Characteristics:
--Occasional Trimming Recommended:
As with most all Boxwood varieties, we suggest a light trimming / shaping be performed 1 - 2 times per year to enhance foliage density & maintain overall desired shape.
