You just put in your location, and it will tell you what it is.
This is important to know for knowing what plants are hardy in your area, how long plants will grow, and also to know if it changes at all. Like ours used to be 3, but they have moved to to 4 now, which doesnt seem like much, but it can be depending on your area.
