Maine giant sequoia
Amies tree - A friend of the family brought my daughter Sequoia this back from CA about 3 or 4 years ago. In the summer it goes outside. I usually put it at the edge of the woods. It seems to like it there. It stays out until about November.
George Melvin created an enclosure for his giant sequoia for winter protection with success.

I water the tree some and weed it once in a while but have tried to see how it fared in our climate. This is from Readfield east of Augusta. Tree was purchased from Welkers in 2007 and grew 11 in. and doubled in width
