LATIN NAME: Thuja sutchuenensis
COMMON NAME: Sichuan Thuja
Plant Profile
Thuja sutchuenensis, commonly known as Sichuan Thuja, is a tree. The Sichuan thuja spirals flat, fan-like sprays of scale-like leaves along upright, branching twigs, reddish-brown bark peeling in thin strips, and the whole tree carries the fine, vertical habit of the true cedar allies. Foliage keeps fresh, deep green tone through year, small, oblong cones ripen to brown, and tree holds narrow, columnar shape that formal garden likes. It is one of rarest of conifers, known from few wild stands in high valleys, and cultivated trees carry the same quiet, handsome character. Gardeners value it precisely for this blend of qualities.
Science & Biotechnology
Botanists studying the Thuja group regularly include Thuja sutchuenensis in comparative work, and the species also appears in horticultural trials aimed at gardeners and growers. Genetic work checks health of remaining trees, nurseries raise seedlings for conservation plantings, and wood and foliage chemistry keep researchers interested. Continuing work by breeders and collectors keeps good seed of this species moving through the trade.
Uses & Benefits
Sichuan Thuja brings genuine presence to the garden and earns its keep across the growing season. In the garden, the Sichuan thuja offers rare, formal presence with columnar habit and year-round green. Dense, scaly foliage makes fine hedge or specimen for sheltered spot, and cedar-like scent of foliage is a pleasure in passing. Its story, a tree once nearly lost and now planted in collections worldwide, adds to the appeal. It establishes readily and then requires nothing out of the ordinary.
Arborvitae is a premier hedge conifer; its thujone-rich oil limits internal use to professional territory, while its name, tree of life, recalls the vitamin-C tea that saved early explorers.
Growing from Seed
Raising Sichuan Thuja from seed is straightforward. Sow thinly on the surface of a loose, well-drained seed compost, cover lightly, water in gently and keep the tray in a sunny spot with even moisture. Shift the seedlings into small pots as soon as they can be handled, and give them bright light until planting-out time.
Our Take
Its long record of traditional use, described above, gives the plant a story beyond ornament. Within its genus it stands out for garden reliability. In a sunny, freely drained position it needs little looking after.
