That is a nice looking specimen. Apparently they grow reasonably well in Seattle - at least, there used to be some of them at the arboretum and they could very well still be there alive and well. I got one from Forestfarm in 1998 or something. It was cutting grown and developed as a big long branch. It is still crawling slowly along the ground and never developed an upright leader.

Here is mine Jason do you have the Chinese form?

Gosh, I'm possibly being a foolish reductivist but if it grows so well for you in FL, it concerns me whether it could every really be hardy this far north. (of course, I wouldn't apply the same rule to plant from North America, since our climate is far more continental, in the sense used by horticulturalists, than SE Asia)
In any case, pictures of the mature forms in Taiwan are quite luscious and I had to try it. IIRC there's the thought the form Camellia Forest has (flodsiana?) might be a bit hardier.

We are growing taiwania and it does very well in central va. One is south facing with a brick wall behind it but the other is in a mixed conifer border and seems quite content.

are there sources for this plant in the southeast? Georgia or South Carolina? thank you

Like Baldcypress and Dawn Redwood, it appears to be hardier than its origin would suggest. Does OK in Britain, though slow from lack of summer heat.

This one in southern Switzerland, quite a good size (about 20m tall), with adult foliage and coning:

Resin, you spoil us.

Nikki,
We got ours from Archtrees.com in North Carolina in '06 and again in '07. We also grow Taiwania flousiana which we got from the same nursery.

Mcpotts

Can you post a photo of your Taiwania flousiana

Thanks

Very nice !!!

How about a blue one...

Coniferjoy, where was that photo taken? Is that your specimen? Very nice pics all.

Taiwania flousiana

Thanks

Nice plant.

Ian, the pic of the blue one was taken in 2010 during the British- and Dutch Conifer Societies fieldtrip in Belgium and France.
This specimen is at the Chevreloup Arboretum in France.

Wish I had room for one of these but they do get rather large in time. As for sources in the SE, check out Camellia Forest Nursery. Not sure if they have them listed in their current catalog but I know they had quite a few they were propagating from cuttings the last time I was up there late this summer.

Man you're lucky! I wish I had a hook-up like you have. Gotta love it.

See these photos has rekindled my desire to growth Taiwania from seed.
I think I will start again the search for seeds.

They are many years that I control a fine specimen in the Botanical Garden Borromeo on Isola Madre on Lake Maggiore. Zone 7a.

The gardeners have told me that he never produced cones, it seems that the only specimen in Europe that produces cones is that of the Dusseldorf Botanical Garden.

The photos are from September 25, 2011, I've taken on Isola Madre and in the last two we see the bluish color of the leaves.

The next picture was taken a month before at the Botanical Garden of Geneva.

Completely misses the bluish color. The gardener is convinced that it is a specimen obtained from cuttings of non-apical branch.

Lake Maggiore is located at the foot of the Alps and the winters are quite rigid. Temperatures of - 15 C occurred several times.

But the Lake Maggiore, near the Lake of Lugano, in Swizerland, where he probably was photographed Taiwania of pineresin, benefit from the effect of the mass of water that increases by 5 to 10 C the temperature on the islands and along the shores.
During the past February, at my house, which is located about 15 km the crow flies,
from Isola Madre, the temperature has remained for 5 days at -17 C. The winter was exceptionally cold and late but on the island the minimum night temperature is not fallen below -7.

Sorry for the boring numbers but maybe it can help you better understand the hardness of Taiwania.

This year during my visits in August and October, I could see that the plant has not suffered and is in great shape instead were damaged some Brugmansia and Dicksonia australis.

Good heavens. Isola Madre is more like zone 9, not 7a. Colletia, Butia, Washingtonia, tree ferns, Amaryllis belladonna, heck Bougainvillea grow there unprotected. The gardeners told me the typical winter low was -4C. That's zone 9. On the similarly situated Brissago, there are many proteas, aloes, Anigozanthos, a large Phoenix canariensis, citrus, etc. Even an Araucaria heterophylla!

A lot of people don't understand how to apply the USDA zones system to the rest of the world (apparently even a # of people who live here don't even understand how they work) and the Lake Maggiore area is one of the most incorrect places in the world to make a comparison because the typical seasonal minimum (i.e., the "zone" temp) is barely below the average winter lows. Only a few other nominally temperate climates are similar in this respect: parts of Japan, etc.

So, thanks for the pictures...but let's leave the determination of USDA zone hardiness to less unique climates.

Thank you davidrt28 for your clarification.

The English is not my language and I am not able to use it properly.

I wanted to make it clear that we should not blindly follow the instructions of the maps showing climate zones

As you quite rightly pointed out the islands of the lake have a much milder climate of the surrounding regions

I share your opinion that the climatic conditions indicated on the maps should be taken with prudence and you should always inform observing what grows in gardens and parks as close as possible to where you want to try to grow our plants.

I hope I was clear and have not worsened the confusion that often exists on this topic.

No problem baobab. Thanks again for sharing the pictures.

I apologize for the late question, salicaceae, I've been reading this just now.

I see you did get seeds from Taiwan Forest Research Institute, I tried looking on their website but couldn't find if they're still selling them or not. Since I'd prefer getting them from the source rather than from one of the online sellers, is there any way you'd suggest to go after this? Do I have to ask them thru the university I'm in or something institutional like that?

Thank you

btw the growth of Jason's is very impressive to me. My 4 year old plant from Camforest has grown agonizingly slowly. It was cutting grown though. Maybe 3 inches a year, and that's more out than up. I'm planting it out with the hopes that it will make it grow faster. I am seeing this with the Taxodium hybrids from Dr. Creech. In containers they just won't grow very fast, but they go berserk when they "realize" they are in open soil.

I've twice had success growing Taiwania from the seeds at Sheffields. They seem to germinate decently (a fair amount of cone remnants and vacant seeds), although last year I struggled making the leap from germination to actually growing. I had two 4-6 inch seedlings by fall. The bigger one died unexpectedly before I could get it planted, but the other survived the winter in the ground and has grown some this year. This year, I managed to get about 15 seeds to germinate, and I just got them in some potting soil, so here's hoping I get a few more going.
