cannot escape the challenge of male and female
relationships, even in the garden. This is most evident in
the large, bright red fruit on the aucuba. Well, you didn't
think I was talking about human relationships, did
you? If you
are wondering why your aucubas do not have red fruit, then
that's were the sex discussion begins. You see, Canadian
geese mate for life and aucubas do, too! I suppose the male
aucuba doesn't really pick out one particular female aucuba,
but he really spreads his love around. If you
are catching on now, you realize that there are male and
female varieties of aucuba, and both must be in the garden
to get the prized red, winter fruit. The
aucuba is one of the best shrubs for the South, even though
it comes from the Himalayas and Japan. Many of you will find
it strange to know they are in the dogwood family. The
variegated forms brighten up the shade garden better than
almost any other shrub. They are almost as pretty as the
tropical croton, and actually there is a variety called
crotonifolia. There
are also green-leafed types. Though there are variegated
females that will produce the large red fruit, I am partial
to the look produced by the huge, colorful fruit up against
a backdrop of deep green. They almost look
artificial. Place
your aucuba plant in partial shade to shade; they abhor full
sun. Prepare the soil by incorporating 3 to 4 inches of
organic matter, and two pounds of a 5-10-5 fertilizer per
100 square feet of planting area, tilling deeply.
Dig the
planting hole three to five times as wide as the rootball
but no deeper. When you dig these large holes, you are
opening the door to the fastest root expansion and
establishment in your bed. Place the plant in the hole and
backfill with soil to two-thirds the depth. Tamp the soil
and water to settle, add the remaining backfill, repeat the
process and apply mulch. Moisture
is critical the first year on newly planted shrubs, so water
deeply when required. Feed four weeks after transplanting
with a slow-released fertilizer like an 8-8-8 or 12-6-6 at
one pound per 100 square feet of bed space. Fertilize
established plantings in March. Prune
lightly anytime to shape and keep bushy. To generate new
canes, remove older ones near the base during the late
winter. Occasionally, mealy bugs can be a problem so treat
as needed, but don't let this deter you from planting some.
Try
planting aucubas boldly in groups around fatsia for a
tropical look. I have seen green types with the fruit grown
very effectively near camellias like Professor Charles S.
Sergeant that has dark-red, anemone-type blossoms. Bedding
plants work quite well as companions. Grow lilac-colored
impatiens in front of the more brightly variegated forms.
If
indeed you want the winter landscape-enhancing red fruit,
then variety selection is critical. Unfortunately, many
aucubas are sold generically, but there are about 25
varieties in the trade. This means it is possible for your
favorite garden center to locate male and female varieties
for you if they don't have them already. Some of
the best-known variegated female varieties are Crotonifolia
(male by this name also listed), Variegata, Nana (compact),
Picturata and Gold Spot. Green female varieties are
Hillieri, Rozannie (said to be self fertile), Salicifolia
and Serratifolia. Male
variegated forms are Maculata, Mr. Gold Strike and Gold
King. Green male types are Augustifolia and Crassifolia.
As you
can tell by the varieties, it may still be difficult to
accomplish the task even if you don't purchase generically.
Talk to your nurseryman about your goals with not only the
aucubas, but also your landscape in general. Think
of it this way: by planning, you are acting like a dating
service, and thus your winter landscape will become much
more colorful with bright red berries in the years to come.

To
be perfectly honest, sometimes there needs to be a little
more sex in the garden. Yes, gardeners, we need to discuss
the "birds and the bees."
