Randy is right, I also think the trachy fortunei is the hardiest. There is also
Trachy Wagnerianus just as hardy but the leaves are stronger and will not hang down due to the winds.
The best thing to do is to get a big tree, it will be more hardy. Plant it in
spring so it can root before the winter. Now , some people protect the
grow-point in the winter against the rain, but I never did that or they spray
with anti-fungus in spring when there is rot.
Take care for a well draining soil, that is very important.
I have stones all around the base of the stem to protect
the ground for freezing.
