Platycladus orientalis Seeds | Oriental Arborvitae
LATIN NAME: Platycladus orientalis (syn. Biota orientalis)
COMMON NAME: Oriental Arborvitae, Bai Zi Ren
Plant Profile
Known to gardeners as Oriental Arborvitae, Platycladus orientalis (syn. Biota orientalis) is a noteworthy species. The flowering period doubles as a feeding season for bees and other pollinators. For the small amount of care it requires, the return is remarkable.
Science & Biotechnology
Botanists studying the Platycladus group regularly include Platycladus orientalis (syn. Biota orientalis) in comparative work, and the species also appears in horticultural trials aimed at gardeners and growers. Tree itself carries deep cultural significance across China, traditionally planted at temples and grave sites and closely associated with longevity and remembrance in Chinese cultural tradition, a symbolism documented extensively in Chinese cultural and horticultural history. Its behaviour in gardens is well recorded, thanks to a long history in cultivation.
Uses & Benefits
Oriental Arborvitae works well in borders, containers and dedicated beds. Bai zi ren seed remains an ingredient in traditional Chinese herbal formulas associated with calm and sleep support, and as with any medicinal seed, appropriate use is best discussed with a qualified herbalist. Living tree itself is also widely planted ornamentally, particularly in formal and memorial garden settings, reflecting its long cultural association with longevity and remembrance across Chinese tradition. A plant that has settled in will get along with only routine care.
Arborvitae gives two classical Chinese herbs: the leafy twigs, Ce Bai Ye, for cooling blood and stopping bleeding, and the seeds, Bai Zi Ren, a gentle calming tonic for sleep and dry constipation.
Growing from Seed
Seed is the natural starting point for Oriental Arborvitae, and the process is uncomplicated. A period of cold, moist stratification helps seed germinate evenly, after which it should be sown into a loose, well-drained mix. Full sun suits this hardy evergreen conifer well, and once established it grows into a dense, columnar specimen valued both for its distinctive form and its long cultural significance. Use a loose, well-drained seed compost, sow evenly over the surface and cover lightly, and keep everything evenly moist in full sun. Pot the young plants on as they grow, harden them off gradually, and plant them into their final positions when sturdy.
Our Take
It is a solid representative of the Platycladus group, true to type from seed. Young plants want steady water; older plants take conditions as they come.
