This NPR map looks wrong in some places, I would just trust the actual USDA map https://planthardiness.ars.usda.gov/ https://planthardiness.ars.usda.gov/
For instance, the NPR source says that Portland, OR was reclassified as 9b, whereas the actual USDA map says that depending on your elevation, it's still either 8a or 8b.
