This tall, airy tree is native to the West Coast where it can reach 300 feet tall. In our area, a height of 80 feet is more typical. The 3-inch cones have distinctive three-pronged bracts. It is named for the Scottish botanist David Douglas who introduced the seeds into cultivation in 1827, and for the naturalist Archibald Menzies who discovered the tree in 1793. The flat needles grow 1 to 1½-inches long.
