Lori McWhirter, via Facebook asked:

Why can some plants resist freezing and others can't?

Answer

This is an evolutionary trick as winter comes along in cold environments.  These particular plants have learned how to change their chemical metabolism, starting to produce more of the sugars and the alcohols that allows them to survive the overall wintering period.  But obviously, not all plants will do that.
