 Now why do they say that about Zone 8 plants???  Is there some reason that 
 mulching won't help them survive in a cooler climate?  like they can't 
 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.
