Climate Change Hits American Yards
An updated hardiness map for plants from the U.S. Department of 
Agriculture reveals just how much local climates are changing
By Jennifer Weeks   

A new spring bloom: U.S. gardeners might have to head back to the 
drawing board because the flowers that can flourish in their area 
have likely changed in the past decades due to climate change.

As winter retreats northward across the nation, gardeners are 
cleaning tools and turning attention to spring planting. But climate 
change is adding a new wrinkle, and now a standard reference - the 
U.S. Department of Agriculture's Plant Hardiness Zone Map - is about 
to make very clear how much rising temperatures have shifted planting 
zones northward.
