So I went to look for the Lewisia I have pictured in the first post of this thread, and at present, it is lost within my pot ghetto.
But now, 2 weeks after that big snowfall, I have some others germinating at the 40°F temperature regime:
Lewisia rediviva from wild collected seed in the Wenatchee Mtns, and
Lewisia rediviva from garden collected NARGS seed
Oxytropis viscida - unscarified seed planted in early spring 2013. Only seven seeds, so 2 full years and the third season seems to be the magic number.
Also
Fritillaria stenanthera and
F. sewerzowii so far.
