Despite its name, Douglas-fir is not a true fir. It is native to Utah and other western states. Utah State University describes flat, blunt needles attached singly to the twig, with foliage ranging from yellow-green to blue-green.

Its hanging cones offer a particularly useful clue: a three-pointed woody bract projects from each cone scale. Young trunks have smoother gray-brown bark with resin blisters; older trunks develop thick, rough bark. Compare the cones and needles together rather than relying on color alone.
