Where the data comes from

Hardiness zones are from the 2023 USDA Plant Hardiness Zone Map ZIP code data (1991-2020 mean annual extreme minimum temperature), produced by the PRISM Group, Oregon State University, prism.oregonstate.edu, accessed 2026-11-03. This site is not the official USDA Plant Hardiness Zone Map; for the official map see planthardiness.ars.usda.gov. A ZIP code can span more than one zone.

Frost dates: NOAA National Centers for Environmental Information, U.S. Climate Normals 1991-2020, annual/seasonal freeze probabilities (doi:10.25921/4ek7-fk11). Some ZIP locations from GeoNames, licensed under CC BY 4.0. ZIP areas from the U.S. Census Bureau. Elevation data available from U.S. Geological Survey, National Geospatial Program, queried through Open Topo Data. Planting rules come from university extension publications, cited on every page that uses them.
