Mark, All I can tell you is my experience. I've moved mine to our unheated greenhouse in winter and left the pot dry until spring when I start watering again. Most years that has resulted in blooms although there was one year they didn't come up. This year bloom was late but all the corms bloomed. So they can survive a dry dormancy, but I don't know if that is what they want. I have a faint memory that I tried to make these winter growers early on when I didn't know when they grew and that resulted in my losing all my seedlings. My greenhouse gets down to almost freezing at night, but is warm during the day so my dormant corms get a range of temperatures.
