Camellias
and other winter plants
BY
RACHEL FOSTER
I get a few questions every fall when camellias
produce their improbably showy flowers. Aren't they a bit early,
people ask? Well, no. Fall-blooming camellias (Camellia sasanqua)
come out in October every year. Sometimes the show is cut short
by an early freeze. This year, at least right here in town, the
weather remained frost-free until mid-November, allowing us to get
full value from the camellias and a couple of other broad-leafed
evergreens – all of them excellent garden shrubs that just
happen to bloom in autumn.
Camellias are certainly the grandest of these, with
flowers in a variety of colors. White, apple-blossom pink-and-white,
light pink and deep pink is the basic range. Some have double flowers
a good two inches wide. Others are single, the flowers up to three
inches across with a conspicuous cluster of yellow stamens. Late-blooming
'Yuletide' has deep red single flowers that are smaller than average
but very abundant. A few varieties of C. sasanqua are lightly
fragrant.
The plants vary in growth habit, too. Some are a
little lax and mounding, while others (especially 'Yuletide') are
boldly upright. None is quite as stiff and formal-looking, though,
as spring-blooming Camellia japonica. Flowers on C. sasanqua
are most prolific with at least half a day of sun, but the plants
grow and bloom quite satisfactorily on a shady wall where most other
plants would sulk. Some varieties are really easy to train on a
wall or a trellis, and their moderate growth rate makes camellias
a good choice for containers.
For serious October fragrance, nothing beats Osmanthus
heterophyllus (holly osmanthus). The pure white flowers are
tiny but numerous, and the scent will carry a long way on a warm
fall afternoon. If you can, plant it somewhere sunny, where it will
bloom abundantly and adopt a better form. Don't worry if a new plant
fails to bloom: Flower production will increase as the plant matures.
There is nothing wrong with plain green holly osmanthus,
but there are several varieties with distinctive foliage. The leaves
of 'Purpureus' (which is said to be the hardiest cultivar) are maroon
purple as they emerge, becoming dark green and lustrous. They show
off the flowers nicely. 'Variegates' has leaves heavily marked with
cream and is one of the best variegated evergreens for our area.
'Goshiki' has yellow-speckled leaves. All are relatively slow growers
that can be controlled easily by pruning.
Strawberry tree (Arbutus unedo) is a close
relative of madrone, but this popular compact form is much smaller.
It is not as small as books and labels say, however, so don't expect
it to stay below six feet forever! Strawberry tree will adapt to
sun or shade and becomes quite picturesque in old age if left unpruned
when the shreddy, red-brown bark becomes more visible. This is a
workhorse of a plant that may go un-noticed until October, when
the bell-shaped, ivory flowers appear in clusters similar to those
of madrone. It often sports, at the same time, spherical scarlet
fruits that spent a whole year ripening.
Camellia and osmanthus are excellent as hedging
plants, and unlike the popular cherry laurel and Portugal laurel,
they are not (as far as I know) invasive. Strawberry tree looks
best as a single specimen or planted in small groups, and old ones
look marvelous under-planted with hardy cyclamen and perhaps the
beautiful variegated form of evergreen Iris fetidissima —
both of which are, like strawberry tree, drought tolerant.
Winter jasmine (Jasminum nudiflorum) is an
honorary evergreen. When the tiny leaves drop off in autumn the
stems remain bright green. Thus it looks very much alive even before
the bright yellow flowers appear. A hard frost can kill unopened
buds, but the light freezes that are far more common in fall will
damage only open flowers, leaving some buds to open over a period
of many weeks. (My plants, like many others I know, bloom in November
and December, but I'm told that some specimens don't bloom until
after the new year.)
Most jasmines twine, but winter jasmine is a floppy
shrub. It tolerates drought, neglect and a fair amount of shade.
It is happy — and spectacular — sprawling over a bank
or a retaining wall, but it is easy to train on a post, wall or
trellis, where it takes up much less space. The flowers are scentless.
You can't have everything. When you get back in the garden in early
spring, cut off or shorten the stems that carried flowers. Prune
as hard as you like: The long green shoots that grow during spring
and summer will carry next winter's flowers.
