Now why do they say that about Zone 8 plants??? Is there some reason that

anything resembling a freeze?

Cold hardy plants have a number of diffrent ways to cope with coldness.
The main reason plants die when it gets cold (below freezing) is that their
cells die from ice. Water freezes and forms crystals that brake the cell
walls and membranes.
Plants have adapted by pumping the water out of the cells (late frost and
plants wilt)
Or by means of a number of diffrent chemical antifreezes.
Those plants that are adapted to more southerly locations do not have these
mechanisms or if they do they are not as pronounced as those plants that grow
in the North or in high altitudes.
