About This Tree
A large, majestic conifer with a straight trunk, horizontal branching, and an open, pyramidal crown that often becomes more irregular and picturesque with age. Known for soft, bluish-green needles in bundles of five and cylindrical seed cones.

On young trees, the bark is thin, smooth, and greenish-brown. On mature trees, it becomes dark gray-brown, thick, and deeply furrowed into wide, rectangular, scaly ridges.
Growing Information
