Thanks for your comments.

Although L. autumnale is frequently quoted as 'hardy', I agree with your
comment and find it is not reliably so here.  It abhors ice on the leaves
and a healthy clump is reduced to mush by only a couple of ice storms, or
re-freezing of melting snow.  It is hardier without a covering of snow/ice
and, like many of the winter-green crocuses, performs just fine at air
temperatures down to 10F, as long as the ground doesn't freeze hard for
extended periods.  I grow my L. autumnale in pots now.  Crocus goulimyi, for
example, shows no leaf damage in response to cold air and frozen ground (as
long as there is excellent drainage) but the leaves burn back badly from the
tips if there is a lot of snow and ice.  Leaf burn doesn't seem to affect
bulb increase though, most of the hard work is done by the time the end of
winter comes and the leaves are a mess.
