B. microphylla var. koreana X B. sempervirens 'Green Velvet'
Green Velvet Boxwood is an extremely hardy hybrid boxwood variety that is especially well suited for use in the southeastern US, due to its increased tolerance of warmer climates & higher humidity. Nice dark green foliage is quite typical for the boxwood species, with minimal bronzing occurring in winter. Bronzing will be more pronounced in colder climates, or in areas where they are exposed to more severe wintry conditions ( winds, etc ).
This variety of boxwood will get slightly larger than some of the smaller, more dwarf versions.....but can be maintained at lower widths & heights through regular trimming / maintenance. Probably not the ultimate choice for those situations where extremely low height is needed ( know gardens, low formal hedging, etc ), but a perfect fit for situations where a nice, neat, evergreen hedge of approx 4-5 feet high is needed. Very, very nice boxwood variety - holds up very, very well year after year - one of our best sellers, period.
Plant Facts & Specifications
Mature Height: 4 - 6 ft
Mature Width: 5 - 6 ft.
Growth rate: Moderate ( 6"-8" avg per yr )
Sun Exposure: Full to partial sun - will even do very well in partial shade areas.
Soil Preference: 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.
Recommended Spacing: A spacing of about 24" - 30" apart is recommended for most typical medium height 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.
