You know, four years ago when I was in Churchill, Manitoba (located in Hudsons Bay) I saw Kannikinick (I hate trying to spell that word) growing wild all over the tundra. I was amazed to see it up there.
I don't know if it was introduced or if it is native up there.
(I do know that it doesn't detur a hungry polar bear
Just kidding, the polar bears were down on the beach and I was sitting on a rock watching the Northern lights)
