"Based on the latest comprehensive weather station data, The Arbor Day
Foundation has just released a new 2006 arborday.org Hardiness Zone
Map which separates the country into ten different temperature zones
to help people select the right trees to plant where they live.
The new map reflects that many areas have become warmer since 1990
when the last USDA hardiness zone map was published. Significant
portions of many states have shifted at least one full hardiness zone.
Much of Illinois, Indiana, and Ohio, for example, have shifted from
Zone 5 to a warmer Zone 6. Some areas around the country have even
warmed two full zones."
