“My God. It’s full of stars.” This is what Dave Bowman exclaimed when he looked into the monolith orbiting Jupiter in the classic science fiction movie 2001: A Space Odyssey. If he had looked at a mountain hemlock, he might have said the same thing. The needles at the tips of the twigs often look like tiny stars with bright blue-white beams of needles radiating out from a point. The needles of other hemlocks tend to lie flat and have white stomatal bands only on the lower surface.
Mountain Hemlock grows in the higher elevations of the Cascades and Olympic Mountains, often at the timberline with subalpine fir and whitebark pine. Below the timberline, it sometimes grows in pure stands of large trees. However, at the timberline, it often remains a dwarf, creeping shrub, where winter snow flattens it to the ground. In these park-like settings, the hemlocks also grow in clumps, which contain one or more old, large trees and several young trees. The range of mountain hemlock extends into the High Sierras of California, where it grows at higher elevations, the northern Rocky Mountains, and along the coast of Alaska to Anchorage, where it grows down to sea level.

As you gain elevation when hiking in the mountains of Oregon, you will see mountain hemlocks growing among the western hemlocks, starting at about 3500 feet elevation. By the time you reach 4500 feet, the western hemlocks give way to mountain hemlocks. However, you don’t have to drive up to the mountains to find mountain hemlocks. You can see them planted as ornamentals in urban areas. Look for the bluish color and the drooping top. They thrive even at lower elevations, but grow slowly, which makes them a fitting landscaping tree.
