Hi Burgos and welcome to Orchid Board
I don't grow any outside, but there are orchids which grow in the wild in the the UK and they would have to by able to stand snow and freezing temperatures during the winter.
The ones I have seen growing wild are Dactylorhiza which have very tiny flowers, but I believe there are others.
This website in the UK sells a mixture of hardy and semi-hardy orchids (the semi-hardy might need taking in or protecting at some times of year). Their catalog includes various types of orchids, including some Cypripediums which I was very suprised to find out could be hardy in UK conditions.
