Thanks for the map.
I live in Southern California where there are a zillion micro-climates because of the hills and valleys, large and small. What grows on the next block does not necessarily do well in my yard.
It’s almost been hit and miss, but these maps do help.
I only wish I could enter my zip code to get a bit more specific.
You can enter your zip code at the site but remember that's the zone for that post office and not necessarily your garden. Type in the surrounding zips just in case. Check the state map link and zoom in to make sure if you're close to a boundary.
You need to look in the Sunset Western Garden Book, newest edition you can find. If you don’t want to buy one (but you should have it!) either check the local library; or see if one is available to consult at a good garden center, local garden club, or such.
Their maps take into account many more factors than the USDA maps, and divides into (IIRC) 24 climate zones for the Western states. The SoCal maps are quite detailed.
