How this checklist is sourced
USDA defines the hardiness zone, NOAA normals provide the typical frost anchors, and each crop's extension source supplies the planting offset. Broad season-only notes are kept on plant profiles because they do not change from one zone page to another.
- USDA Plant Hardiness Zone Map, 2023 by USDA Agricultural Research Service / Oregon State University PRISM Group. the USDA hardiness-zone band.
- U.S. Climate Normals 1991-2020 by NOAA National Centers for Environmental Information. the median spring and fall freeze dates.
Local conditions vary.
