But we don’t get the subfreezing winters. Maybe they don’t need chilling hours like some of our temperate fruit varieties that originated in those areas do.
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.
