The wild blueberry bushes I have seen were less than two feet tall. They seem to do well enough through hard Quebec winters with no help.
This was my experience in Minnesota, Wisconsin and in southern Ontario. Low bushes, but I was young and the picking wasn't nearly as hard as it would be today. I did pick huckleberries in the Mission Mountains of Montana that grew on bushes that were as tall as I am (6 feet).
The best blueberries ever were in pies made on Quetico canoe trips back in the early '60s. 5 or 6 days into an 8 day trip, blueberry pie made in a reflector oven, made with fresh berries that grew all over the island we camped on. Nothing in the world could taste better than such a wonderful sweet treat when you're 50 miles back in the wilderness.
