In autumn, the foliage turns a rich orange to bronze, illuminating the landscape before dropping to reveal the tree’s picturesque silhouette. Small, inconspicuous flowers bloom in late spring among the foliage, and female blossoms become small, rounded cones-first powdery blue and then brown. They arise from seasonal, deciduous stems that are oppositely arranged on the permanent, upward-reaching branches. The needle leaves are soft and bright green with two lighter green bands on their undersides. With age, the trunk becomes broadly grooved and buttressed at its base. The bark is shredded and reddish brown, eventually becoming beautifully gnarled and rugged with chocolate brown and orange tones.
