I have had pretty good success with many of the acid bog-loving 
terrestrials (rescues from construction and other human activity).
You have to make sure that they stay moist at all times and get 
full sunlight.  If grown in pots, they should be protected from 
extreme cold (such that it would freeze through the pot - temps
of 20 degrees F or lower).  

The one orchid that I would most heartily recommend is Pogonia
ophioglossoides.  It is nearly impossible to keep it too moist, so
setting the pot in a shallow dish of water and keeping it filled will
keep this orchid happy.  It also has the lovely habit of reproducing
vegetatively, so the number of flowering stems of a properly grown
plant will increase over the years...sort of like a terrestrial
pleurothallid.

Here is a photo of Dr. Wil Neptune's plant... all those growths
are from one original individual:
