RE: CULT: Plant Zone Hardiness Map

The map is based on reports from 7,000 stations, up from 5,000 the last time
it was done. There is bound to be many local variations, microclimates as it
were, that are not shown on the map. The more stations they have out there,
the more accurate the map will be.

The zone map now has my location in Zone 8.  However, I have lived in what
used to be and still is considered Zone 8 in the southernmost part and it is
very different than my growing conditions in what is shown as the middle
part of Zone 8 now.  Many plants are not compatible from the two parts of
Zone 8.  The zones are a loose guideline often, I would think.  If the
growing conditions vary that much in just the Texas portion, I wonder how
much more variation there may be from the dry western portions to the much
higher rainfall eastern portions.
