The Softwoods - Conifers
A very beautiful evergreen tree, the Port Orford White-Cedar is a large tree, 80 to 200 feet high and 3 to 10 or 12 feet in diameter. The younger trees have short, feathery, weeping branchlets of deep yellowish-green and a dense, pyramidal, narrow rounded crown. The branches are pendulous, lacy and droop conspicuously. The short, ﬂat leaves are scale-like and overlap one another, are soft, closely pressed to the twigs and like other cedars have a pleasant aromatic odor. The cones ﬁrst develop as small reddish-brown, soft berries, then mature in a cone of dark russet-brown, having shield-shaped, overlapping scales. The trunk is clear of branches 80 to 100 feet from the ground. The bark is ﬁve to eight inches thick at the base of mature trees and becomes thinner as the well-shaped trunk reaches for the sky. It is ﬁbrous, dividing into deep narrow, rather loose ridges and separating into long strips or thin shreds of a deep reddish-brown. The tallest Port Orford Cedar is at Coos Bay, Oregon, and is about ten feet in diameter. Port Orford White-Cedar is also locally known as Lawson’s Cypress in honor of Sir Charles Lawson, an eminent economist of Scotland for whom the classical name “lawsoniana” was given this species.
