Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Thuja plicata Common Name: Western red cedar Family: Cupressaceae Author: D.Don. Known Hazards: None known Mature Height: 60 Mature Width: 12 Habitat: Grows singly and in small groves in moist to swampy soils, usually in shady forests, from sea-level to 1350 metres[60, 82, 99].
Cultivation Notes: Prefers a moist loamy soil[1, 81]. Dislikes dry soils[11]. Not suitable for light sandy soils because it is shallow rooting[75], but it succeeds on most other soil types, even on waterlogged soils and heavy clays[81, 200]. Succeeds in chalky soils[200]. Prefers some shelter from the wind according to some reports[1, 81] whilst others say that it is fairly wind resistant[11, 75]. Trees tolerate salt winds[75] but not severe maritime exposure[K].
The wood and foliage are highly aromatic[226]. The foliage has a strong fruity smell, like pear-drops or crushed apples[185].
A fast growing tree, it often puts out new growth of 1 metre a year and can average 60cm a year for the first 40 years. Increase in girth can also be rapid, 5cm a year for the first 60 years has been recorded[185]. Sometimes planted for forestry in Britain[17], it is at its best in the moister western half of the country[11, 185].
There are many named varieties selected for their ornamental value[188].
Tolerant of light trimming, so long as this is not back into old wood, plants also retain their lower branches unless these are shaded out by neighbouring plants[11].
The foliage turns bronze in cold weather[81].
Trees are notably susceptible to honey fungus[81, 200].
