Eastern Hemlock (Tsuga canadensis) - Eastern Hemlock Trees

The Eastern Hemlock (Tsuga canadensis), the state tree of Pennsylvania, is one of the dominant trees of the Commonwealth's forests. The tree can grow to a height greater than one hundred feet and is found in every Pennsylvania county, but most commonly in the mountainous regions. This slow-growing long-lived tree thrives in the shade and may take 250 to 300 years to fully mature and may live for 800 years or more. The hemlock, identified as an evergreen tree, has flat needles 1/3-2/3-inch long and 1/2-3/4-inch cones that mature from September to October.
