Hardiness Zone Map 2024 By Zip Code. Enter your zip code in the search box to find your location in the plant hardiness zone map. Using your zip code or by looking at a map, you determine what plants can grow outside in your garden.

This new map version used gis technology and input from climate, botanical, and horticulture experts to create hardiness zones on a much finer scale. If there are several hardiness zones in that zip code, zoom in on the interactive map to find your exact location.
