I've now done this in the Chicago area with C. bulbispermum, Ellen Bosanquet 
and unknown I got off of eBaya .  They have survived 3 years outdoors, no 
mulch; planted at 24" from the foundation of my house  which has a basement. 
They've not yet bloomed, but I wouldn't be surprised to see it one fo these 

We have had as much as 2 weeks of zero or single digit days in one of those 
years.  The below ground temperature where they're planted ( 1 foot down), 
I'm sure stays sufficiently warm even tough it appears to be frozen for 
months.   They are upand growing at this time, about 2 feet tall along with 
the two lower-growing Eucomis and mixed unknown Zantedeschia hybrids growing 
at 20" from the house all of which have now been grown outdoors for 3 years.

Jim Waddick is warmer than I by about an average of 10° and that much ahead 
of me (two weeks?) in terms of growth and release from dormancy.
