The Mountain Hemlock is possibly the least adaptable of the hemlocks. In its native habitat it attains a height of 50 to 90 feet, but it is slow growing and smaller under cultivation. The needles are a blue-green to gray-green color and give a bottle-brush effect by growing all around the stem. Cones are 1/2 to 3 inches, cylindrical, hanging down from the branches and are purple when new. It thrives where the growing season is short and winters are long and cold.
