So I was cruising around the internet trying to find out what hardiness zone I was in exactly because I have heard anywhere from 4 to 6. It seem most sights list us at 5b or 5a.
But while I was looking for this I found a heat zone map. I have never heard of a heat zone but it makes sense. Here is the link below.
