I grow the radiata in a clay pot in a peat coir mix. After it is deciduous about once a week on a sunny day I drizzle water around the edge of the pot to keep the tuber from totally drying out. The temp is never below 60 degrees.
If the plant has a wide enough range it could be likely. I keep Spiranthes odorata which ranges from NJ to southern FL. One from the Glades couldn't need much cold during its dormancy! it might pay you to try to find a supplier located someplace warmer.......
