Yea
I agree Gary thats why I left one seedling outside for winter.
I have found that it is very difficult to get smaller Trachys,Sabals,Needle palms etc through the cold winters here as they are less sturdy than more developed plants.
If this seedling survives the winter,it will be very exciting to see how it's hardiness compares to other palms.
This is why I am trying so many palms of varying size and using 6-8 different protection strategies.

Which is exaclty what we should be doing. Trail and error. Let us know how the different methods work out Jim, I'll be interested in hearing the results!

Garry- Good info on the native range, I didn't realize that the native range of T. fortunei was known! I'm trying not to comment on the technicalities anymore (it's boring for everyone but me, I'll just let my professional training rot me from the inside out!) so I won't pursue my argument for why some of the technical terms we're using are inappropriate...

Keep up the good work and look forward to more interesting pics and comments from plant habitat! The pics you posted of the green 'princeps' are interesting...

Paul,
I think it is interesting as it could broaden our vision and sharp our thoughts by listening to a different standpoint, I am interested in discussing those sort of things with you , Jim and other guyswho share the same interest as me. Anyhow some terms are not properly used by us , that does not prevent us from enjoying the fun the talk brought us. Even science theory is not perfect and needs to be improved as time goes , so are our ideas.The point is we gotta just have an open mind to all the things in front of us .It is a good experience and pleasure we could obtain from exchanging the ideas with others.
Jim, the palm seedling is not as hardy as the adult and you may use some protection in winter .Say cover them with fallen leaves or sawdust or bark which are rotten to produce some heat to warm them in winter. Only in the ground, they could develop good roots adapting the climate faster.
Did you guys grow T.princeps-nova by yourself and how did it go there?

From what I read, there is a Dutch guy said he went through -23C if I understand correctly at cemunnos.nl .A French friend said his T.princeps-green of 20cm trunk survived the cold spell of 2008 and 2009 in France .He put it at fousdepalmiers.fr forum "Very Interesting the German experience up to -20° !
For my TRACHYCARPUS Sp Nova has suffered minimum a month as freezing
the maximum recorded was -18.6 °. All of my Trachycarpus Fortunei very close to this Nova are all died !
For my Trachycarpus Sp Nova, they grow very fast"
It is confusing.

Yea Garry it all is confusing sometimes.
As far as I'm concerned there are so many variables involved with the types of freezes these survive that I can't really judge each plant by what I read.
T.wagnerianus has been a very sturdy and tough plant in my trials,I have only lost one and I think it was sick to begin with so I throw that one out.
In my experience cold hardiness is really found in individual plants and I think most of this depends on it's health in the first place.
Out of Europe we hear Oreophilus and Latisectus are not as hardy but all there cold hardiness is tested in wet conditions for the most part.
I believe Kristoff had a Latisectus survive teens (F) as I recall it was seed planted in the ground and kept dry during winter.
These 2 factors more than anything,(1- seed sowed in the ground and 2- kept dry)appear to be the best bets going 🙂
