Some years ago, I got 3 mulberry trees even though they were iffy in my area. Officially we are zone 4b/5a, but I've found I have to buy zone 3 rated trees to have them survive long term. This past winter we got down to -35.6 F. Every year they would come back, but they would get so much winter kill that they never produced anything. Finally the massive grass fire that burnt down our house put them out of their misery.

Ugh. We seem to have a little bit of everything on the property here, but I haven't seen any mulberry, so I bought some. The Missouri conservation department has a nursery and we can get certain natives extremely cheap. I think they'll be fine now since they should have down some decent roots. We're 6a.
I would think 6a would be fine.
I live in a river valley and the cold sinks down into the valley and gets colder than our official zone. When you add 60+ mph winds multiple times during the winter, it can be brutal on man and trees/plants. Our harsh weather keeps the crowds away though.
