I grow some Disa hybrids in my bog bed outdoors (right of the decking in the bottom picture) with Sarracenia's and other marsh orchids.
Intermediate conditions are far too warm. In winter they should just be frost-free, but some types withstand short periods of light frost. So if you live in a milder area, you should be able to grow these outdoors.
We had a really cold winter, down to -8C this winter for a couple of nights and most my plants perished. But this orange hybrid (5 plants) seems to be the hardiest and has survived.
