Zones for cities in Virginia
Using your zone in Virginia
Zones measure winter cold only: the average of the coldest night each year from 1991 to 2020. Within Virginia, zones change with elevation, latitude and distance from large bodies of water, so two towns a short drive apart can differ by a half zone or more. Check your own ZIP code, then pick perennials, shrubs and trees whose tag range includes your zone.
What changed on the 2023 map
The 2023 map, released by the USDA and Oregon State University's PRISM Climate Group, uses weather data from 1991 to 2020 and far more weather stations than the 2012 map. Nationally, about half the country moved to the next warmer half zone and the rest stayed in the same half zone, so if your plant tags or old garden notes use a 2012 zone for Virginia, it is worth checking your ZIP code again.
