| Osmamthus
heterophylus "Goshiki" |
 |
Osmanthus
bear a superficial resemblance to holly, and
share a similar leaf
shape and general plant habit, though they
are from a different plant family. While they
do not produce those familiar red berries,
osmanthus are notable for their fragrant blossoms,
which appear on established plants in late
summer into fall, and their uses in the landscape
are similar. "Goshiki" is one of
the most striking, with spring foliage emerging
in shades of orange, cream and pink before
settling in to its usual pattern of green
marbled heavily with gold. People often have
mixed reactions to variegated plants, with
some folks loving them and others finding
them a bit unnatural. You can usually count
me among the former, and this is especially
true during winter, when my eye is drawn to
the splash of color they provide.
While not hardy in coldest zones, Osmanthus
are very adaptable otherwise, and will grow
in sun to part shade in a wide variety of
soils. "Goshiki" grows more compactly
than the regular O. heterophylus, and makes
ideal foundation plant, as well as small to
mid sized hedge or speciman plant in a mixed
border. Needless to say, it is also a natural
for a Japanese garden, and can be kept to
most ant size desired with a little pruning.

Pulmonarias
are indispensable in the woodland garden,
providing both floral as well as foliage interest.
These excellent plants have been saddled with
the common name of "Lungwort", hardly
an appetizing thought and originally applied
due to the resemblance in the wild forms of
P. saccharata to lung tissue with their spotted
leaves, and these were thought at one time
to have medicinal properties related to lungs
due to that resemblance. Don't let the name
fool you, though, as these are first rate
garden plants.
In "Excalibur", the metallic, silvery
color covers nearly the entire leaf surface,
leaving only a thin green edge, and seem to
glow in a shady border. Spring blossoms arrive
as soon as spring temperatures rise just a
bit, as early as February in some climes,
and are fairly long lasting, changing from
blue to pink as they mature. It is the foliage
that is the real show, though, and after blossoming
the leaves provide interest until heavy frost
cuts them down. These are very hardy plants
in all but the most extreme climates, and
"Excaliber" is little troubled by
the mildew that can affect some other Pulmonarias.
Just give it a rich, moist soil in a spot
with dappled to half sun and enjoy.

| Chaenomeles
"Toyo Nishiki" |
 |
|
|
Few shrubs are as rugged and adaptable as
flowering quince, and their bloom is one of
the real heralds of spring. The traditional
red flowering quince is a familiar sight,
growing nearly everywhere with equal ease,
but many people might be surprised that it
comes in colors other than the familiar red.
Of these, the cultivar "Toyo Nishiki"
is one of the most striking and well worth
seeking out. With it's blossoms ranging from
pink to white to red, all on the same plant
and sometimes even on the same flower, this
one is a real attention grabber, and like
any flowering quince, the branches can be
cut in winter and brought inside where they
will provide bouquets of blossoms at a most
welcome time.
This will form a mid sized shrub to six feet
or more in time, but can easily be kept smaller.
It isn't at all fussy as to soils or water,
and is hardy enough to survive all but the
most inhospitable gardening areas. Try it
in a mixed border where it will get the blooming
season off to an early start, or in a more
formal Japanese garden where it's zig-zagging
branches can be used to great advantage.

| Gaura
lindheimeri "Crimson Butterflies" |
 |
|
| This
new intoduction may be appearing in your local
nurseries this year, and it's a real knockout.
Instead of the tall, and often wispy plants
produced by your typical species gaura, this
one is short and stocky, and the blossoms are
the darkest yet. Best of all, the foliage is
a screaming burgundy color, especiallly pronounced
in early spring, and so providees a wider season
of interest.
Gauras are very easy to grow and require little
other than a spot in the sun and reasonably
well drained soil. Despite being native to
areas of the southwest, they are quite hardy
and will surive sub zero temperatues. They
can exhibit some leaf spotting in early spring,
especially if cool and moist, but soon outgrow
this as the weather warms. Once the plants
seem bloomed out, just shear them back fairly
hard and you will be rewarded by more blossoms
and renewed foliage. At two feet in height,
these are more easily worked into a small
garden than their four foot counterparts.

| Syringa
patula "Miss Kim" |
 |
|
|
Is
it possible to really dislike lilacs? Perhaps,
for the tall French lilacs often outgrow their
spot in the garden, and produce those intoxicating
blooms too high to really appreciate. Add
a bit of mildew, a bit too much familiarity
and it's easy to understand that they might
be taken for granted. Put those blooms at
nose level, though, throw in some mildew resistance
and even a little fall color for good measure
and you have a real winner. No wonder "Miss
Kim" is so popular.
Miss Kim is a different species than the taller
S. vulgaris types, with a decidedly more compact
growth habit. They will generally top out
at 6-8 feet or so, but can be kept smaller
with a little judicious pruning right after
flowering, so can fit in to even the smallest
gardens. They are extremely hardy, and will
grow happily in all but the mildest winter
areas with just routine care. As a harbinger
of spring, they can't be beat.

| Growing
plants in hanging baskets has really taken off
the last decade, due in part to the success
of "Supertunias" and other plants
marketed for such use. There seems to be no
limit for the number of new plants introduced
each year as people continue to explore the
growing of plants in containers, and it's no
wonder -- for a few dollars, we can create little
miniature gardens in exactly the colors we desire,
and with good care they will continue to blossom
for months on end. If you like supertunias,
you might look for this years new introductions,
"superbenas".
Although many people might refer to many of
these hanging basket plants as annuals, they
are actually tender to half-hardy perennials,
and the superbenas are no exception. They
will survive several degrees of frost, especially
if planted in the ground, and so can be used
as a perennial in zones 8-10. For most folks,
though, they are better used for summer color,
and this is a role in which they shine, for
wil regular water and feeding, they will continue
to bloom until after first frost. If you have
been disappointed with some of the older,
annual strains of verbena which soon become
infested with mildew, you might try these
new "superbenas", which are stronger
growing and more resistant.

Clematis
are often called "queen of the climbers",
and with such a variety of color and form,
is it any wonder? People are often attracted
to the gaudy, large flowered hybrids, but
the genus is rife with smaller flowered gems
that make up for lack of flower size with
their ease of growing and multitude of blossoms.
You would do well to consider some of these,
and Betty, here, is one of the best.
Betty Corning is often listed as a C. viticella,
but is thought to be a hybrid between C. viticella
and C. crispa, and was discovered growing
in a New York garden in the 1930's. What serendipity,
as gardeners have enjoyed growing her ever
since. With a long blooming season which can
extend from summer and into fall, Betty produces
masses of dainty, bell-shaped blossoms of
a soft lilac color and satiny sheen. The pendulous
blossoms have a light fragrance and have a
grace and charm all their own. While the flowers
may look delicate, the plant is very vigorous,
and is capable of growing 10 feet in a season.
A good, hard pruning in early spring will
help keep it in bounds if necessary, but this
is one of the great ones for scrambling up
into trees if left unpruned.

| Vitex
agnus-castus "Chaste Tree"
|
 |
|
|
Though often more of a large shrub than a
tree, Vitex is invaluable for providing color
in a mixed border right when so many other
plants begin to wane. This underused plant
is in the same family as butterfly bush and
with similar spires of blossoms, and like
it's relative will attract bees and butterflies
to the garden. It has a far better plant habit,
though, as instead of the gawky, ungainly
growth of a butterfly bush, chaste tree will
form a rounded dome much more suitable for
the general landscape. Its aromatic foliage
is untroubled by the mites that plague butterfly
bush as well, so chaste tree is certainly
worth a look for those who want the look of
butterfly bush but without the drawbacks.
Vitex is unfussy as to soils and watering,
and enjoys as much heat as it can get. In
areas around zone 6 or below, it can act something
like an herbaceous perennial when cold nips
it back, but in warmer areas will grow anywhere
from 8-15 or even 20 feet when allowed.

| Salvia
azurea "Nekan" |
 |
|
|
The genus salvia sports many garden worthy
plants, but quite a few of them are too tender
for the average garden. One of the hardiest,
and more adapted along a wide range of climates
is our native S azurea, which grows through
the plains states and midwest, producing its
glorious true blue blossoms at a most welcome
time in late summer and earlier fall. It can
be a bit of a lax grower, though, requiring
either a good shearing or some staking to
keep it from flopping. Selected from wild,
"Nekan" (named after Nebraska and
Kansas) has been chosen for its stockier plant
habit, which makes it an excellent candidate
for the mixed border. This is an easy grower
with flowers larger than the species, and
that true blue mixes well in just about any
color scheme and will provide a nice pick
me up during these "dog days". Just
give it a spot in full sun and don't overwater.

| Cotinus
"Grace" |
 |
|
| Few
plants are as capable of lighting up the fall
landscape as smoke trees, but the interest doesn't
stop there as this one is an excellent choice
for a season-long display. The lush, almost
transparant spring foliage on "Grace"
emerges in shades of red in spring before turning
bluish green in summer, and then topped off
in summer by huge clouds of pinkish bloom --
the "smoke" in smoke trees. The fall
color is truly spectacular, especially when
situated in a position where it can be back
lit by the sun as the leaves turn anything from
yellow to orange to a sort of pinkish-red that
seems to glow as the light passes through the
leaves.
Smoke trees are easy and hardy plants, and
are quick growers -- hitting 20 feet or so
if left unpruned. They can also be used as
a large shrub, though,and if pruned heavily
in spring can be kept to about half that height
or less. They are drought tolerant when established
and are an excellent choice as a specimen
plant or patio tree or in a spot in a large
mixed border.

| Pernettya
mucronata |
 |
|
|
You may find these listed as Gaultheria as
taxonomists bat around the genera a bit, but
no matter the name, these make excellent choices
for providing a spot of color through the
fall and winter months.
They
may not be well known, but these little evergreen
shrubs are like a southern hemisphere counterpart
to our northern blueberries, lingons and huckleberries,
except that the fruit is not edible. They
are all season performers, though, with new
spring growth showing bronzy hues and small
white blossoms that develop into variously
colored fruit -- typically red or
white, but on some selected cultivars with
colors ranging from blush pink through rose
and into shades of plum and amethyst. Best
of all, the fruit lasts for many months from
late summer, right through winter and even
into the following spring.
Like their blueberry cousins, pernettyas like
a spot in half to full sun (a little shade
helps in hotter areas), and a well drained,
acidic soil. Plant several for best berry
production, and these make a good choice for
a small, informal hedge, or as a smaller foundation
plant. Those below about zones 6 or 7 will
need to provide them some winter protection.

Poinsettia
Euphorbia pulcherrima |
|
|
| This
native of Mexico is synonymous with Christmas.
Named for Joel Roberts Poinsett, the US ambassador
to Mexico in the early 19th century, it represents
more than 85% of the plant sales during the
holiday season. With a little care, it can last
for several weeks beyond Christmas.
In
nature, this perennial shrub can grow to ten
feet tall What most people believe to be its
flowers are actually colored bracts, or modified
leaves. For many years, the typical holiday
plant was a bright red, but now there are
over 100 varieties in shades of red, pink,
burgundy, white and even yellow.
When
choosing a poinsettia, make sure the foliage
is green right down to the soil line. Dont
buy a plant that is sleeved in paper or plastic,
as they will not last as long as one in an
unadorned pot. Try not to buy a plant that
has been crowded with others, since crowding
can cause bract loss. Make sure the soil is
not wet, as root rot can be a problem that
will shorten the life of the plant.
Exposure
to low temperatures can damage a poinsettia,
so make sure it isnt out in the cold
(an unheated car, an outdoor porch) for more
than a few minutes. Keep near a sunny window,
but dont allow any part of your poinsettia
to touch a cold window. Keep away from cold
drafts and direct heat, including areas near
an exterior door. A daytime temperature of
between 60 and 70 degrees, and a night temperature
of 55 are ideal. High temperatures will also
shorten the life of a poinsettia. If possible,
at night, move to a cool room.
Check
the soil daily, and only water when the soil
is dry Make sure the pot has adequate drainage
and dont let its feet get wet.
Punch holes in the pot, if necessary to assure
good drainage. If you keep it past the holiday
season, a good houseplant fertilizer should
be applied once a month.
