The USDA is reportedly redrawing its plant hardiness zone map this year. Last time the map was updated was in 1990, although the National Arboretum Web site does indicate that their map was revised in 2001. The map above is part of an update I found on the National Arbor Day Foundation site. Areas in pink represent territory which had shifted one zone warmer between 1990 and 2006.
I'm making a stencil to plaster the map on a gallery wall to accompany my Twittervore video.
