So what is the Plant Hardiness Zone Map?

The USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which perennial plants are most likely to thrive at a location. The map is based on the average annual extreme minimum winter temperature, displayed as 10-degree F zones and 5-degree F half zones.

This has been updated as of November 15,2023. We were formerly in zone 7b but now are in zone 8a.

Go to the Plant Hardiness Website and plug in your zip code to find out the Hardiness zone you live in.
