The garden zones move north

U.S. Department of Agriculture

The U.S. Department of Agriculture has released a new version of the “Plant Hardiness Zone Map.” As you might expect, a warming climate has pushed the zones north. It’s the first time the zones map has been revised since 1990.

It’s interesting to note that the Department of Agriculture isn’t saying anything about global warming. Though the data is obvious, we can’t risk offending the oil companies and the know-nothings.
