Winter hardy orchids?

[Kittyfrex]

Title might sound a little misleading, but i had no other ideas.
The climate i live in is...odd. Altrough there is a distinct winter, the only thing that ever makes it frigid is a strong northen wind that normally blows from late autumn to late spring. Except it hasn't. The last 8 years i have been living here, and a few when i lived across the small seaway, the climate had shifted not as much to warmer as to...more even? That particualr wind had been absent last two years and while temps didn't pass 20 C, it was more than enjoyable. I had a bunch of normally tropical plants outside, under an overhand that stopped rain but still in 6+h of full sun, includng, but not limited to, C. arabica, M. deliciosa, Golden photos, F. Benjamina. My banana plant is loving it parhaps too mcuh; i'll have to repot it this year even tho the pot weighs twice as much as me; she is going into the ground.

My dendrobium nobile had been growing outside for the last two years, and would be a damn huge plant if not for snails that seem to love him in the winter. And according to all I've read, Cymbidiums don't mind dipping just under 4°c if dry. I've put mine out too late, so no blooms i guess, but it immediatly started growing and much faster than while it was on a window inside.
Are there any other hardier orchids? They don't need to tolerate snow or frost, just ocossional drops in temperature (lowest we had was a -1 one night, but the water never actually froze outside; the next lowest was 5). I've read that Brassia rex would fit the bill, but the post was old and i haven't stumbled upon anything else elsewhere.

I am sorry for all of the confusion i caused.
