Growing Neofinetia in garden, in Europe

[Jakob]

Hi,
so i got an idea

since my elementary school years i had been under impression that USA, Europe and Japan had basically the same climate and are approximately equally north. When i started growing orchids i figured out that's not true, Europe is way more north than either of the two (Tokyo being equally north as Athens, and New York being equal to Madrid...). This is quite beneficial if you like cold growers, as they do quite nicely here, but for experiments like growing orchids outside i imagine is not very helpful.

But, as climate does work in mysteriuos ways, that Europe, while not as warm as Japan and USA, is not significantly colder (yay gulf stream).
So i got a (maybe) stupid idea to try and grow some of the subtropical epiphytes in continental Ljubljana.

Why I think it might work - Ljubljana lies near the edge of subtropics in Europe and there is some effect of the mediterranean climate in winter, so days, when it doesn't go above 0°C are rare, and even if it stays under , it usually a degree or so under, nothing radical . We get one (1) coldsnap per year (with temps down to -10) if we were good boys and girls so we can go skiing, but in the valleys it usually not that bad. Especially in Ljubljana it's always a bit warmer.
There's also some garden plants from mediterranian and subtropical, like figs, Canna, some palms, and kiwi etc. manage to get by.
With a picture of what I will be dealing with, lets get to the questions.

I read somewhere that Neofinetias range from 32-36 degrees latitude. Is that true? Could anybody point me in a direction of a distribution map? Does it grow in mountains and how high up?
If there's someone from Japan here, that lives where Neofinetia grows, could you describe the winters you have?
Thank you very much but there's not a lot of literature in English (or I don't find it) about that stuff, and unfortunately I do not speak Japanese.

I think it would be awsome to have to have orchids growing in a natural way in the garden.
