I've been growing Allium zebdanense here in Zone 5  (30 miles west of 
Chicago) in the shade garden for more than 10 years now. I do not mulch 
the area. During this period we've experienced low temps ( -28 F) with 
no discernible damage to the ever expanding clumps.  I have noticed  a 
minute amount of self-seeding. 

However, a friend in the same general area, has hundreds of these bulbs 
in her very humus-rich 5 acre shade garden where they self-sow with wild 
abandonment.   Wish I could get mine to self-sow as much!

I have also seen them thriving at Boerner Botanical Gardens, in Hales 
Corners, WI near Milwaukee.
