Berberis thunbergii atropurpurea
widely used shrub for hedges, accents, and borders. Foliage has a
purplish / red shade to it, along with a nice deep green base color.
Very, very prickly thorny "barbs" are present on all the branches,
which makes this plant a great natural barrier. Can be trimmed / pruned
to maintain virtually any desirable shape and size. Very hardy shrub -
can withstand a wide range of soils & conditions. Has been an
extremely popular shrub selection for years & years with no sign of
slowing up in popularity.
Plant Facts & Specifications
--Mature Height: 3 - 6 ft
--Mature Width:4 - 6 ft
--Growth Rate: Moderate ( 6" - 8" avg per yr
--Hardiness Zones:4 - 9 ( if unsure of your zone, please use zone finder below )
--Sun Exposure: Full sun to partial shade - best growth rate & color in sunny spots. Loses it's red intensity in shadier locations.
--Soil Preference: Average, slightly moist - well drained. Will adapt to a wider variety of soils than most Barberry.
--Foliage Color & Texture: Small
leaves with dark red / burgundy color in sunny locations. Fall color is bright
orange / red.
Branches are generously covered in very sharp, spiny barbs. Newer growth is especially bright red, maturing to a darker burgundy color.
--Flower, Cone, Or Berry Facts: Small
white flowers can be observed in little clusters beginning in early
April, and lasting well through the end of May. Exact flowering time
will vary, depending on your area of the country - the warmer your
climate, the earlier you will see them. Small 1/4" long bright red,
oval shaped seed pods can be easily seen on Red Barberry in
late fall, after the leaves have dropped. Each bright red seed pod has
one seed in it, and will remain on the shrub throughout the
winter....giving it a very nice winter appearance as well.
--Diseases / Insects:Usually
barberries have little or no trouble at all under normal landscape
conditions, but some of the possible noted pests / diseases that could
be encountered are: Bacterial leaf spot, anthracnose, root rots, rusts
(Japanese Barberry is not susceptible), wilt, barberry aphid, barberry
webworm, and possibly scale.
--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.
