Zones

The zones represent the lowest average temp that an area receives. The
USDA produces the map most people reference. The USDA's page explaining
the map and zones is he http://www.usna.usda.gov/Hardzone/index.html

Reading various post on this NG it seems to me that Zones relate in some way
to temperature. Here in the UK it is either hot or cold. :-) So could some
kind person let me have a list of these Zones and related temperatures, if I
am correct in my assumption..
