Coast Redwood Sequoia sempervirens
The Coast Redwood, is a conifer native to the fog-bound coastal strip which stretches from Oregon to south of Monterey in California. The tree was introduced to Britain in 1843. In its native habitat it can grow to over 110m in height but in Britain not more than 40m. It is now common in formal gardens, estates and parks. It grows better in the north and west. The tree has two types of leaves, scale-like leaves on the main shoots and needles on new growth. The needles are not opposite one another as in the Dawn Redwood. Its closest relative is the Giant Sequoia which has only scale like leaves.
The Dawn Redwood, the Coast Redwood and the Giant Sequoia (sometimes called the Sierra Redwood) are all related. They are relics from a period 100 million years ago when they were widespread. They now have very restricted natural distributions – the Dawn Redwood to central China and the other two to California.
