Thuja orientalis seed

LATIN NAME: THUJA ORIENTALIS

COMMON NAME: Oriental Arborvitae

In the old temple courts and the sheltered gardens of the east, the oriental arborvitae grows as a compact, evergreen conifer with the dense, upright sprays of flat, scale-like, yellow-green leaves, the small, upright, barrel-shaped cones and the reddish, fibrous bark. The plant steadily develops a narrow, conical crown, often reaching 5-10 metres. It is content in the sun or the light shade and the well-drained soil.

Scientific Research & Plant Biotechnology

The oriental arborvitae comes up often in the studies of the hardy conifers of the east Asian gardens, its dense, upright sprays and its tolerance of the dry air keeping it in view in the work on the formal hedging and the container conifers. The research looks at the way the flat sprays hold their colour through the year, the small upright cones ripen and open, and the seed biology of the winged seeds.

Ecological & Economic Value & Wide Applications

Around the old courtyards and the formal borders, the oriental arborvitae holds its neat, upright green through the year and takes the clipping that shapes the hedge and the topiary. The dense foliage gives the winter shelter to the small birds, the fibrous bark has served the traditions of the region, and the tree makes the fine hedge, the specimen conifer and the container plant. It is a conifer for the sheltered, well-drained place.

To grow the Oriental Arborvitae from seed, sow the seeds in drills on a gritty seedbed and cover them very lightly.

Sow the seeds in drills on a gritty seedbed and cover them very lightly, and keep the young conifers in the open, sunny spot. The flat green sprays firm up through the season.

 

 

 

 

LATIN NAME: Platycladus orientalis

COMMON NAME: Chinese Arborvitae, Oriental Thuja, Biota, Chinese Thuja

The Chinese arborvitae is a noble and long-lived tree of eastern Asia, and it has been planted at the temples and the tombs of China for centuries. The young plant grows into an open, airy crown, to about twelve metres. It is a native of northeastern parts of East Asia and North Asia, and it is a very hardy and durable tree, grown as an ornamental and as a tree of the temple and the garden, while its wood has been valued for a long time.

The Chinese arborvitae is the only species of the genus Platycladus, a monotypic genus of coniferous trees in the cypress family, Cupressaceae. It is native to northeastern parts of East Asia and North Asia, and it is also known as Oriental arborvitae, biota or Chinese thuja.

Scientific Research & Plant Biotechnology

The Chinese arborvitae has a genuine and distinguished place in both botanical and applied research. It has been studied in botany, since it is the only species of the monotypic genus Platycladus, and researchers have examined its classification, its relationships with the other members of the cypress family and its long history of cultivation, making it of interest in the study of the conifers and of plant taxonomy. The tree has also been studied in forestry and in the research on tree planting, since it is a very hardy and durable tree, and it has been planted for centuries at the temples and the tombs of China, while its durable, fragrant wood has been valued for building and for carving, so its cultivation and its uses have been examined. The species has also been studied in horticulture, since it is a valuable ornamental conifer, and many cultivated varieties have been selected. For a tree of such long history and such hardiness, the Chinese arborvitae has a rich and growing record of research.

Ecological & Economic Value & Wide Applications

Ecologically, the Chinese arborvitae is a generous tree of the garden and the grove. Its dense, evergreen crown gives shelter for birds, and its cones feed small mammals, while it has been a noble presence at the temples and the tombs of China for centuries.

Its economic value is real. It is a very hardy and durable ornamental tree, widely planted in gardens and along avenues, and its durable, fragrant wood has been valued for building, for carving and for other work, while it has also been used in traditional medicine and as a tree of the sacred groves of China. For a grower, the Chinese arborvitae is a hardy and dependable tree, and for a gardener it brings dense, evergreen beauty and a long history. The seeds are easy — sow them in a pot of free-draining compost in spring, keep them lightly covered in a sunny spot and water them gently, and theyll sprout within a few weeks, growing on into a hardy, evergreen tree.

Thuja orientalis, widely known as oriental arborvitae, delivers great landscape and ecological value across temperate planting zones. Its dense evergreen foliage forms compact screens, works well for boundary hedges, and offers shelter for small local wildlife. Beyond ornamental use, parts of the plant hold practical value in traditional herbal applications, making it a multi‑purpose woody species for diverse planting projects.

Growing this species from seed brings notable advantages. Seed‑raised plants develop robust, deep‑reaching root systems that support long‑term hardiness. Large‑scale propagation through seeds is straightforward, allowing many healthy young specimens to be produced from one seed batch. Seed‑grown stands adapt smoothly to local site conditions over time, building stable and resilient plant communities.

Prepare clean, well‑drained growing medium with balanced organic content before sowing. Fresh viable seed responds well to moist pre‑sowing conditioning, which primes internal tissues and sets the stage for steady, even sprout emergence. Scatter seeds evenly across the surface and cover them lightly with a thin layer of substrate. Keep the sowing bed steadily moist without waterlogging, and place containers or seedbeds under bright indirect light.

Under suitable moisture and temperature conditions, seeds will awaken and push fresh shoots upward. Young seedlings grow steadily, developing fine green scale‑like leaves and strengthening their root network day by day. As small saplings mature, they tolerate open sunlight and cope well with ordinary garden soil. With basic ongoing care, these young plants will steadily grow into full‑sized evergreen specimens, bringing lasting green coverage to landscapes year‑round.
