Hi all

Since Alberto showed his beauties, I decided to go on with the world needle tour and show my little babies.

It is pretty much impossible to get any larger specimens without being completely ruined. So, to try and see, I firs planted out a tiny seedling in April 2012:

post-6290-0-53786700-1422049489_thumb.jp

It has put out 3-4 leaves every year. We lack summer heat so I'm happy anyway. It has never had any sort of protection.

and it's already showing some needles, yaaay.

post-6290-0-48299300-1422049857_thumb.jp

And here's my larger one. Planted in spring 2013. Unfortunately, I have no comparison shot. It's in semi shade.

Good to see you.

Hmm.

Bet you could get Trachies to grow, fortunei, that is.

Thanks Dave, I do in fact have a T. wagnerianus, a T. princeps "hybrid" and a T. geminisectus planted out. For the princeps hybrid and the geminisectus it's the first winter. They look fine so far. We have had lot's of snow and some -7/-8C and once -10 ( on december 29).

I only started growing exotic plants in 2012 and I'm therefore still testing what is possible. I also have some desert plants (A. ovatifolia, Y. thompsoniana for example) which are very trouble free and rewarding.

Nice Needle Palms, Flow! What sort of absolute minimum temps do you see there?

Frank, I do not know the exact minimum but usually it is between -10 to -15C altough -15C is rare. The average minimum in January is -2.7C according to Wikipedia.

There is a private weather station nearby and it recorded -16.5C in 2005 or 06. That is about the coldest we've seen in the last 10 years or so. There was a killer two weeks in 2012 with highs below freezing and temps down to -15 which put an end to many unprotected T. fortunei. It was clearly the duration of the freeze which killed them. Also, the ground was frozen solid pretty deep.

So, to sum up, what kills most exotic plants here is prolonged frost. This also means that USDA zones are pretty much useless here.

This is quite annoying considering the fact that in the south of our small country there are centenatrian Jubaeas, Braheas, Butias and others. And the south is less than 200km away from where I live. Only the alps in between..

Those look very healthy. They are great palms. You will love them more and more as they get bigger. I live in the middle of their native range and the ones in my relatively new garden don't look any better. In fact, I have trouble getting them established. I am thinking they need more water and/or richer soil. Once established they are trouble-free, of course.

Very healty looking needle palms. They survive in this part of Holland as well, but have the same problems with summer heat for some good growth.

Plant it, Troy, mine did not grow well in its pot. But of course, they are never going to be "fast". I wish I could plant Archontophoenix..

So, today I noticed this:

post-6290-0-90642700-1434474827_thumb.jp

First flower ever.

This might be rather boring for some of you but I was very excited to see this and I didn't know they flowered at this size already. The plant only has one tiny sideshoot which isn't growing much so far (barely visible on the photo here on the left).

I had grown up a needle palm from seed in 2003 in a pot, which I placed outdoors in my garden in Germany as long as possible. But due to the extreme fluctuation in temperature during the winter (between +20°C and -20°C in January and February) It was not possible to plant it in the ground. When it was 3 years old it already looked quite pretty:

I gave it away in 2008 to a zoological garden in Walsrode/Germany.

How about a little summer greenhouse for extra warmth?

Fla. climate center: 100-119 days>85 F
USDA 1990 hardiness zone 9B
Current USDA hardiness zone 10a
4 km inland from Indian River; 27º N (equivalent to Brisbane)

Central Orlando's urban heat island may be warmer than us

I had two needles. The smaller one suddenly dried up this spring and died within two or three weeks, no clue why. The larger one is fine. The smaller one had been in the ground since 2012 with no protection.

But it does look like a shrub and doesn't add so much that tropical look to the garden..

Oh oops, I didn't mean to post this here but in the wagnerianus topic where Yunder Wækraus asked about it hence the link - my bad :-)

Btw the flowers of the larger one just stopped developing at some point. I guess that's because it was the first time? It was rather late as well even though we've had a very warm spring and summer.

Way to go Flow!

Needles will take down to about -25 F; -31 C. Nannorrhops might be worth a try if you can give them the hottest spot you have.

Dave, I had a potted Nannorrhops wich grew well during summer and just died in my frost free but rather moist greenhouse in winter..:-(. Anyway, I know of no succesful longterm survival of Nannorrhops around here. Winter wet seems to finish them off quickly.

About needle hardiness: Temps do not normally drop below -12/-15C here, that should be no problem. However, it is never that easy. They sometimes just die for other reasons, as did my small one.
