Evergreen conifer growing to 70 metres
in height in its native western North America. It has a narrow long crown and the top of
the tree (the leading shoot) normally leans over to one side. The bark is reddish brown
with scaling ridges. The leaves are of several different lengths and emerge from the stems
at several different angles. Widely grown in plantations in Western Europe, it can
tolerate lower levels of light than most other conifers.
