What this site is (and isn’t)

Region tracks

Each ZIP maps to a calendar region key. Florida keeps UF/IFAS North / Central / South (north-fl / central-fl / south-fl). Southeast neighbors keep Extension-style subregions; Mid-Atlantic through West Coast states use climate splits such as va-piedmont, ny-upstate, tx-north/tx-south/tx-east/tx-west, and ca-north/ca-central/ca-south.

Sources

Plant calendars and ZIP → zone mappings cite the public publications below. Non-Florida month arrays are guide-aligned with honest approximate / offset windows when full month tables are thinner. Tropicals and some arid or cool-climate specialists intentionally use empty calendars outside suitable tracks.

ZIP → county/zone entries in data/zip-map.json are curated static lookups approximating USDA PHZM patterns for public locations across covered US regions — not an official USPS or USDA product. Confirm your exact zone with the USDA ZIP search before relying on hardiness alone.

Seasonal theme

The UI shifts with data-season and data-region on <html>, driven by week-of-year plus the region key from ZIP. Early fall stays mostly green on Florida-tuned week defaults; late fall accents warm up. Region labels cover SE through West Coast tracks.
