Kiama, Australia |
Dear Readers,
While we were in Australia and New Zealand I discovered what turned out to be Norfolk Island pines growing in the wild. I always think of these attractive trees as indoor ornamentals, but of course they do thrive outdoors, and can grow to impressive heights in their native habitats. They are considered tough trees that make excellent specimen plants.

Planted in Paihia, Bay of Islands, NZ in 1880. |
In America, Norfolk pines (they actually aren't pines at all) can grow up to 80 feet in USDA Hardiness zones 10A through 11, although they are easily damaged by high winds.
Here is the original story I wrote for The Christian Science Monitor about using these graceful plants as holiday trees:
The day we set off to find “the” Christmas tree is one of my
favorite times of the year. It’s usually the day after Thanksgiving when we’re
still stuffed from the holiday feast and in need of an outdoor adventure. I say
adventure because the search for my perfect tree can last an entire day.
Before leaving home, I bring down the boxes of holiday
decorations and set each ornament out on the dining room table. There’s
everything from Woody Woodpecker (who does his famous laugh when you press a
button) to pipe cleaner Santas that belonged to my grandmother.
My rocking
horses, glass turtles and miniature carved birds are lined up, waiting to be placed
on the bushy, beautifully symmetrical Frasier fir soon after it comes through
the front door.

There was no room for a big tree before our big move |
Four years ago when we put our Maryland house on the market,
we decided not to get our traditional tree.
I discovered I really missed looking through the ornaments –
it’s rather like visiting with old friends.
And I missed the festive lights in
the corner where the tree usually stood. So I bought a little Norfolk Island
pine, added a string of 20 lights, a few bows, and voila -- Christmas tree!
It wasn’t our usual statuesque 7-footer, but it did just
fine for that unusual holiday season.
A winter ornamental from the tropics.
Araucaria heterophylla is native to a small island in the
South Pacific that was sighted in 1774 during Captain James Cook’s second
voyage of exploration. The island was named in honor of the Duchess of Norfolk
and the trees seen growing there were estimated to be over 200 feet tall.

Here at home, the Norfolk Island pine is almost always grown
indoors as a compact houseplant since it is far too tender for most areas of
the country.
The popularity spikes
during the holiday season for obvious reasons. But these charming little trees
need not be thrown out with the dried-up Poinsettias once January arrives. With
proper care they will last for many Christmases to come.
Indoor climate is the key.
Norfolk Island pines are relatively easy to grow and make
appealing accent plants all year-round thanks to their graceful branches and
soft, touchable needles. They can tolerate low lighting for a brief time (such
as during the holidays) but do best when exposed bright light.

An hour or so of direct sunlight won’t hurt, but be sure to
rotate the tree a quarter turn every two weeks to keep it from becoming
lopsided.
Despite their tropical homeland, these trees prefer an
environment on the cool side.
Ideally, temperatures should range from 50 and 70 degrees -- anything in the 80’s will likely
cause needle drop.

Norfolk Island pines don’t require as much water as other
houseplants. In fact, they won’t tolerate saturated soil. Give them a drink
only when the top inch or so of soil in the pot feels dry to the touch. Allow
some water to run out of the bottom of the container, then discard any excess
in an hour or so.
In addition they don’t like to be pruned – in fact pruning
can deform these plants. The only trimming required is removing any dead lower
branches. If you prune a tip or healthy branch, the tree will not grow at that
spot again.

Gator ornaments are a must |
Feed your tree lightly every other month during spring and
summer with a fertilizer specifically formulated for indoor foliage plants.
Some experts suggest repotting every three years; others say the practice
disturbs the roots and isn’t necessary.
I didn’t have my Norfolk Island pine long enough to worry about
fertilizing or repotting – I gave
it to a neighbor before we moved to the mountains.
But I must confess even though I missed my heirloom
ornaments that Christmas, the little tree made our holidays merry and bright.
