Gardeners want nothing more than to see their favorite plants thriving. That being said, plant selection can be quite challenging, as there are some many varieties from which to select.
While many factors come into play when considering the suitability of a particular plant, the information displayed within the Oregon planting zones map should always be considered first.
The new USDA plant hardiness map, which was released at the end of 2023, can be seen above. The new map divides the country into growing zones based on 10-degree F. intervals, as determined by climate information compiled over a thirty-year period. The average extreme winter low temperatures for the country were recorded in this weather information.
Zones 5a through 10a are included in the expansive Oregon zones. The southern coastal region is the warmest, with winter extreme lows of 30 degrees Fahrenheit. On the other hand, the cooler regions of the state may experience temperatures as low as -20 degrees Fahrenheit.
To identify which Oregon planting zone you are in, you can enlarge the map above. If you want some more detailed information or cannot find your location on the actual map, you can visit the USDA website where you can input your zip code to find your exact zone.
