Good question, but unless you can keep it above 20 degrees it probably would not make it. Cold hardy to about 18. Some other blue palms are the mazari palm, and some sabals, but none of these make a statement like a bismark. They are expensive, but if you find one cheap and are willing to take care of it during most of the winter, its worth a shot.

Good luck

I would never make it in the ground in zone 6-7. I live in zone 9 and they were hit pretty hard here this winter with 20's! Mine survived at 24* but was badly burned and just now has started to put out some new growth. You might could protect it while small, but before long it would be impossible to cover with their great size.

No it will not survive there and they will not take lower 20s very well and some will die at 25 degrees or look like they had.I only had 30 degrees one night this year and I had two silver ones that were burnt with only two fronds that didn't burn.
