That's hard to understand when the ground freezes so deeply in the upper 
Midwest, and these crocuses start growth in fall. Does the ground never 
thaw during the winter? Are they somehow in suspended animation? How can 
they survive?

In milder, but still cold-winter, climates, repeated freezing and thawing 
are hard on low-elevation Mediterranean crocuses.
