You may see references to plant hardiness zones everywhere as a gardener. Planting zones are mentioned on blogs like this one, written on seed packages and plant tags from nurseries, and even on weather stations.
We all think we know what it means. Simply find your area of the country on the key and coordinate with where the tag says to plant, right?
Well, that’s not wrong, but it’s not the full picture of what planting zones are meant to convey. It also doesn’t take into account weather patterns that can be very different within the same plant hardiness zones.
