Frequently asked questions
What does zone 5B mean?
Zone 5B is a USDA plant hardiness band based on average annual extreme minimum winter temperature. It helps compare winter-cold exposure across places; it is not a planting prescription.
Why is the table sorted by population?
Population ordering surfaces larger communities first. The zone total counts all published ZIPs in band 5B; page through the table to browse beyond the first page.
Is a hardiness zone the same as a climate normal?
Hardiness zones summarize winter extreme cold. ZIP pages on US5 also show precipitation, snow, and FEMA risk context separately.
