Thank you everyone.
Gardenglory, We're near the coast so it keeps our winter lows mild, but we don't usually get the summer heat that the other zone 8's get. So it's a very different zone 8 compared to a lot of others in the US. Washington state has a lot of cold winter areas, there are some as low as zone 4. I'm just lucky to live in it's mildest zone. I agree though, it does seem odd.
