The native sand pine was once grown for Christmas trees. It has a somewhat cone-like form when young. It can also be trimmed to make it more Christmas tree like.

The native red cedar can also be used as a Christmas tree. It tends to have a cone shape too when young. It can also be trimmed.

But both of these will eventually grow into full sized trees though.

Chinese junipers come in many forms. Some stay smaller, and some may be Christmas tree like enough for you. You may want to do a search and see which kind you like best.

I suppose you could even use a podocarpus. It too grows into a tree eventually, but it could be trimmed to any shape or form you like.

I had a weeping podocarpus when I moved in here in "92. The huricanes did it in. It was around the size you are looking for.
I really like the red cedar also.
Good luck with what you end up with!

THANKS FOR THE INPUT FOLKS.I'M ALSO THINKING ARBORVITAE BUT COULDN'T FIND REAL SPECIFICS FOR ANYTHING IN MY SEARCH.NOW I'VE GOT SOME INFO TO START LOOKING AT SOME LOCAL NURSERIES.THERE'S NOT TOO MANY IN MY AREA BUT MAYBE IN THE LEESBURG TO MT.DORA AREA I'LL FIND A GOOD TREE NURSERY.THANKS AGAIN.

Arbovitae will eventually get huge, but they do maintain their shape.

How about a norfolk pine.Sold everywhere.Slow grower.Keep a good shape.

I can only recommend the one that I grow:
I have the Smooth-Barked Arizona Cypress (Cupressus glabra) 'Carolina Safire'.

It naturally has an X-mas tree form, and a pleasing bright blue-green color. Grows fast, and can get bigger than the dimensions you list... but you can prune it whatever shape you like. If not for its outstanding ornamental qualities, I've enjoyed this tree simply because it needs no maintenance at all. In fact, it thrives on dry, poor soil, which I have an abundance :)

Beware of Norfolk Island Pines! They get TALL and spindly pretty quickly, and then they fall down in the slightest wind. One fell on my boyfriend's car last spring here in Miami, during a regular old thunder storm. No hurricane, just a May rain shower. It fell from across the street and smashed up his car pretty good.

They're pretty for the first few years, but a drought here, a flood there, and they get really scraggly looking. And think of all the people who will live there after you.

I had to take one out in Stuart several years ago to protect not just my house, but my neighbors house, and it required topping three times with a bucket truck before they could cut it down. It was very expensive.

PLEASE don't plant them. They're really a menace down here.

I have a NIPine that started out as a table top Christmas tree 11 years ago when I was moving from Baltimore to Orlando and didn't have the time to do regular Holiday decorations. I've kept it in a pot but it's gotten huge - maybe 9 or 10 feet tall. I was planning to put it in the ground, because it keeps falling over in even the slightest wind, but haven't done it yet. Now that I've read the comment here about them falling over even when planted outside, I think I'll put it on the curb and hope a neighbor picks it up! Maybe if I put some tinsel on it first it will look more inviting...

you could donate your NorfolkP to a shelter or other charity for use as a Christmas tree or you could put a notice in Freecycle and it would be picked up in 10 minutes (or less).

Reading Susannah's account (natives/veggies) you prob don't want it in a neighbors yard.

I agree totally with natives and veggies .
People tend to plant NIP way too close to houses and then end up with a tall monster .

From the link :

This large evergreen has a single upright trunk, tiered branching habit, and a narrow pyramidal or columnar shape. Eventually reaching a height of about 80 feet, the tree possesses a rapid growth rate. The tree would grow taller, but lightning frequently limits height growth in the eastern U.S.

Although they provide some shade, they are not suitable for patios or terraces because they are too large and large surface roots are common. In addition, columnar-formed trees generally cast limited shade due to the narrow crown. Many people forget how tall these trees grow. They often have an attractive pyramidal form (like a fir or spruce tree) when they are small, but they quickly grow too tall for most residential sites. They can live as a house plant for a long time if not overwatered.

AFTER VISITING SOME LOCAL NURSERIES AND INTERNET SITES, WE'RE LEANING TOWARDS THE "BLUE POINT" JUNIPER. IT SUPPOSEDLY MATURES AT 15-20' AND IS SLOW GROWING AND TAKES PRUNING WELL.MOST BLOGGERS HAVE GOOD REPORTS BUT I FOUND ONE WHO IS REMOVING TWO AFTER TEN YEARS BECAUSE OF BROWNING OR "DIE BACK".
MAYBE THIS WAS BROUGHT ON BY SITE SPECIFIC PROBLEMS.
HAS ANYONE HEARD OF THIS TYPE OF PROBLEM WITH JUNIPERS OR EVERGREENS?

Denise - thanks for the suggestion! I think I will post a notice on Freecycle. It's too large to fit into any home, sadly. Thanks!

Solstice,

They really are bad trees here. I think it's a climate thing, that they evolved in a world that was much drier - Norfolk Island, Australia - and here, they get too big too fast and can't sustain their height. Maleleuca is similar - flowers four times a year here, and reproduces like crazy, because it's not in its native habitat where conditions and bugs controlled it. So now it's taking over the Everglades and lots of wetlands north of here, actually changing the water table in some places. They're now illegal to plant in Florida.

Norfolk Island Pine will never make that terribly invasive list because they don't reproduce in the wild. But each and every one of them planted in someone's yard is a disaster waiting to happen. You can't water them enough to tide them over during a drought after they've gotten really big, so they grow weak in dry weather. Then they fall.

Honestly, I'd put that pine out with the trash. And I'm someone who does everything possible to not add to the landfills. Chip it and compost it if you can. But it's a bad tree here. On freecycle, someone will come take it and put it in their yard, and they or their neighbors will regret it sooner or later.

Just my personal screed on that blasted tree.

Susannah
