Hi, Jim. I know that the top freezes. I don't know whether the tuber --  
corm -- underground storage organ freezes.

Once they are damaged by cold, the leaves deliquesce, mineralize, become 
compost. They might freeze and thaw a few times in a short period, but they 
are gone quite soon. They don't hang on all winter.
