The Pacific Coast is incredibly mild. There's parts of Alaska that are approaching hardiness zone 8. So it's not surprising further south in places like Victoria BC and Seattle are near a 9. Speaking of hardy palms, this windmill palm is incredibly hardy down into the 7's and can survive in states like Alaska, Alabama, Delaware, Maryland, Massachusetts (my home state), Mississippi, New Jersey, New York, Oklahoma, Tennessee, etc.
Because some winters get very cold temperatures, which are too cold even for the hardiest palm, so they may survive for a few years but they are not long term plants without serious protection...
Atlanta should be OK for palm trees. Its winter lows are above freezing on average. Though I wouldn't risk it because on occasional days it can get very cold. But 1 very cold day won't kill an entire tree, I'm sure.
Even Atlanta is too cold for Palms (at least in the long term). Its continental location means every once it a while it will see bitter cold. The record low in Atlanta is -8 which is almost 20 degrees lower than the record low in Vancouver CA.
You see some palm trees here in some backyards. But in general they can't grow here because there is a real possibility for a decent cold snap with temps below -10c.

And the same happens in marginal areas in Europe. Feb 2012 in Locarno down to 3F. No way Robusta and CIDP survived that along with 6 straight days below freezing. Same thing happened in Toulouse in 2012.
And palms died in the UK in December 2010 with those frigid temps there. And you wanna bet loads of palms died in Europe in the 1980's. Palms died in Madrid in Feb 2012 as well as Rome.
As has been told to me on this very forum, Europe gets crazy cold as well, just maybe not as often. And all it takes to kill palms is one crazy cold winter.

Lol you wanna bet there are palms in Atlanta and Dallas as well. The thing is when they do get very cold there, it usually recovers quite fast. Also, the average temps are much warmer than a place like Locarno or Copenhagen lol. You need to go on some other forums and tell people in Atlanta there are no palms there. I know people growing them.
