Almost anything from the northern half of Japan, Korea, northeastern China, and the higher mountains of western China (Gansu, northern Sichuan) should do well for you.

Avoid species from southwest China and the Himalaya, as they won't be hardy with you.

Ever been to Göteborgs Botaniska Trädgård? They have a very good collection of Asian trees, and are only marginally warmer than you are in winter.

Hi again,

Thanks for the quick answer, could you recommend anything in particular from these regions or guide me to a page that perhaps lists trees you speak of?

Never been to Göteborg, but will surely pop by their botanical garden if I have the time!

Thanks again!

Regards,
Boyd

Before anyone says anything I know Japan and Korea are part of Asia. 2 other plants you mant to consider that are not asian are acer circinatum-Vine Maple and the american PawPaw. PawPaw would be very different if you can get it. David

What an intersting suggestion for anyone in the need of an unusual trees (even in the states) - The Paw Paw tree. I like it and have always been curious about the taste of the fruit. Once a staple of the south, it's been by-passed for other trees that don't seem quite so interesting in hindsight. Even has a folk tune named after it that I learned as a child in Kentucky.
