Chinese arborvitae

Platycladus orientalis

''Platycladus'' is a distinct genus of evergreen coniferous tree in the cypress family Cupressaceae, containing only one species, ''Platycladus orientalis'', also known as Chinese thuja, Oriental arborvitae, Chinese arborvitae, biota or oriental thuja. It is native to northeastern parts of eastern Asia and north Asia, but is also now naturalised as an introduced species elsewhere in Asia.

New spring growth and immature cones on an Oriental arborvitae conifer. The unique looking cones are 15 mm in length and will turn brown over the coming weeks. They are both male (containing the pollen) and female (containing the ova). The pollen from the male cones is transferred to female cones by the movement of the wind and insects through the foliage and then a seed is formed.

A monoecious tree, it is small, slow-growing, reaching 15–20 m and 0.5 m trunk diameter . The foliage forms in flat sprays with scale-like leaves 2–4 mm long, which are bright green in colour but may turn brownish or coppery orange in winter. The cones are 1.5–2.5 cm long, green ripening brown in about eight months from pollination, and have 6–12 thick scales arranged in opposite pairs. The seeds are 4–6 mm long, with no wing.

The branches are relatively short, loosely arranged and, usually, sharply directed upwards, and the bark, brownish, is detached in narrow vertical strips. The twigs are compressed and are arranged in vertical planes. The leaves, arranged in four rows, fleshy, opposite, decussate, truncated, imbricated as adults, somewhat curved inwards, of uniform green color and with a resiniferous gland on the underside. The female cones, of pink-salmon color and later bluish-greenish when immature, centimetric and of annual maturation, are oval with 6-8 flattened, thick scales, coriaceous and provided with an apical hook.

The binomial ''Platycladus'' means "with broad or flattened shoots". The qualifier ''orientalis'' refers to its native habitat in China.

The common name 'arborvitae' is from Latin, 'tree of life', and is based on its association with long life and vitality in Buddhist thought in China. This is probably based on the tree's unchanging evergreen nature in the cold dry climate of northwest China, and its longevity; some of the larger specimens planted around Buddhist temples in China are said to be in excess of 1,000 years old. It is called cèbǎi in Chinese.


It is native to northwestern China, but it is delicate to distinguish the areas where they are native safely from those where they have been introduced. It is distributed in Manchuria, Russian Far East , and now it is naturalised in Korea, Japan, India and Iran as well. It is also cultivated in many parts of the world in parks, gardens, home yards, cemeteries and for hedges.


Resistant to drought, it is very often used as an ornamental tree, both in its homeland, where it is associated with long life and vitality, and very widely elsewhere in temperate climates. It is suitable for form cuts and year-round opaque hedges, but also forms impressive slender solitary trees. Several cultivars have been selected, of which 'Aurea Nana' has gained the Royal Horticultural Society's Award of Garden Merit.

The wood is used in Buddhist temples both for construction work, and chipped, for incense burning. Its twigs and leaves contain 0.12% essential oil containing pinene and probably caryophyllene. The roots contain up to 2.75% of gasoline....hieroglyph snipped...
