Gardeners — What Hardiness Zone Are You In?

The United States Department of agriculture had updated its Plant Hardiness Zone Map, reflecting a more accurate picture of growing conditions in the United States. Canton, Michigan is currently in zone 6a and 50% of the country has a warmer zone assigned. Gardeners, nurseries and plant breeders are among those who use the map. Data also figures into research models for crop-risk insurance and the spread of exotic weeds and insects.
