The eastern white pine can grow up to 80 to 100 feet tall and up to 42 inches in diameter. It has a pyramidal shape, a straight trunk, and delicate gray-green foliage. On young trees, horizontally extending branches are arranged in what are known as whorls. On young trees, the bark is thin, smooth, and greenish-gray; as the tree ages, it thickens, becomes deeply furrowed, and turns grayish-brown. The five-needle bundles are soft, flexible, and have an upper surface that is bluish-green and a lower surface that is whitish in hue. Each of its cylindrical, 4" to 8" long cones has two tiny, winged seeds inside each of its thin, sticky scales. At the conclusion of the second season, the cones will reach maturity and drop.
