When one is looking at plants for their gardens they need to know if they are suitable for the area that they live in.
I recieve catalogs with the various trees,flowers and vegetables in them that you can order.
Each has a zone listing so that you know if you can use them. My issue is that my most recent catalog included the zone information but not the map.
I found this one and hopefully you will all find it as usefull as I have. Good luck and happy growing.
