New USDA Plant Hardiness Zone Map
I posted this on the Annuals forum too, but I figured many people would not see it unless they actually visited the Annuals forum, so I posted here and on the shrub forum too.
Most people probably already know this, but there is a new USDA Plant Hardiness Zone Map effective January 2012. The hardiness zones have either changed or just been updated on the map. For example my hardiness zone, according to the new map, is zone 6b. On the old map my hardiness zone was 6a. It may not seem like much but those few degrees can make a big difference. Below is a link to the new map.
