Oriental Thuja Thuja orientalis

The Oriental Thuja is a conifer native to north-western China. It is also known as Chinese Thuja or Chinese Arbor-vitae. Its scientific name is also Platycladus orientalis, reflecting the fact that it is now thought to be not a Thuja but in its own genus. It was introduced to Britain in 1752 and is common in churchyards and parks. There are a number of very popular cultivars available for planting in rockeries and churchyards.

The Thuja  genus includes the Western Red Cedar Thuja plicata and 4 other species. Thuja varieties are widely available from Nurseries and Garden Centres. There are 8 varieties of Thuja plicata alone in Hilliers Guide. They are used for hedging and screening. Dwarf varieties and full trees are grown as ornamental plants. Thujas are sometimes called Arbor-vitaes (tree of life) after the resemblance of the foliage to the white matter of the brain called Arbor vitae. Click on any photo to enlarge it.
