Berberis thunbergii 'Aurea'
you are looking for contrast in a shrub, you have found it with this
one!! A definite knockout in just about any landscape. Super bright
solid yellow foliage which retains its color well, except for in areas
with lots of shade, where the leaves will then turn more of a lime
green color. A very dense form of Barberry, and is relatively
slow-growing when compared to other varieties of this species. From our
experience with this variety, it will do very well in almost any
location - full sun to part shade. Seems to do best when watered
regularly - do not let it dry out too long - has an above average
moisture requirement. Great for use as an accent shrub, mass plantings,
but really too bright for use as a hedge due to the intense bright
yellow color. May be kept at most any desired height / width through
occasional trimming. A truly wonderful plant!!
Plant Facts & Specifications--Mature Height :
3 - 4 ft
--Mature Width :
4 - 5 ft
--Growth Rate :
Slow to moderate ( 4" - 6" avg per yr )
--Hardiness Zones :
4 - 8 ( if unsure of your zone, please use zone finder below )
--Sun Exposure :
Full sun to partial shade - best yellow color in full sun, more lime green in mostly shady spots
--Soil Preference :
Average, cool, moist & fertile - well drained. Mulching recommended twice per year.
--Foliage Color & Texture :
Deciduous Broadleaf - small
leaves with good bright yellow color in sunny locations. Fall color is
bright orange / red, with leaves persisting well into late fall.
Branches are generously covered in very sharp, spiny barbs.
--Flower, Cone, Or Berry Facts :
Flowers / Seeds - 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 are sometimes seen on Golden 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 :
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.
--Recommended Spacing :
2 ft apart recommended for hedge planting
--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.
