Whether a bulb is "chilled" would depend on whether it is under snow 
cover in winter. Soil temperatures under winter-long snow cover can 
remain remarkably moderate, even in the coldest regions. Situations 
where there are intermittent thaws would be different, and indeed the 
soil might get colder there. This is one reason why in Fairbanks, 
Alaska, where I lived for many years, people were able to grow both high 
alpines and temperate-zone bulbs and perennials in their gardens. The 
snow came in early October and didn't melt until May.

I also tried Halda's Ungernia seed collections but never got the few 
that germinated to live beyond three years.

I enjoyed Vlad's story of the old photo of his great-grandfather with an 
Ungernia, both identified by name.
