Chamaecyparis nootkatensis (common name: nootka cypress)

Propagation: Seed - sow March/April in a seedbed outdoors[1]. The seed is best sown in pots in a frame[K]. Seed can take 18 months to germinate. One month warm then one month cold stratification has produced good results[2]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter, planting them out in late spring after the last expected frosts.

Cuttings in late summer or autumn in sandy soil in a cold frame[3][4][5]. Difficult, it may be best done in late winter to early spring[2].

Cultivation: Succeeds in most soils and situations, but prefers a moist deep loamy soil and a sheltered position[3][4]. Grows well in heavy clay soils. Survives on dry alkaline soils[5]. Does not grow well on peat or shallow chalky soils[4]. Growth of trees is hardly affected by a lack of phosphate in the soil. Plants are moderately shade tolerant, especially when young[6][5]. Plants are tolerant of atmospheric pollution according to one report[5], whilst another says that they do not do well in a polluted atmosphere[3].

Plants are hardy to about -35c, they also tolerate low summer temperatures[5].

A very polymorphic species, there are many named varieties[5].

This species establishes well and grows fairly quickly when young[4]. Trees can reach 20 metres tall in 35 years but growth slows as the trees get older[7]. It is cultivated as a timber tree in Europe[8]. Trees in the wild can live for 1,000 years or longer[9], one specimen is believed to be 3,500 years old[10]. This longevity is probably due to the presence of toxic chemical compounds from microscopic fungi concentrated in the heartwood[9].

The wood and foliage have an acrid odour[9]. The bruised foliage releases a smell of turpentine[11].

Favoured by many birds for roosting, high cover and especially for nesting, large specimens of this tree help to attract songbirds to the garden[5].

Trees are notably susceptible to honey fungus[5].

Range: Western N. America - Alaska to Oregon.

Habitat: Woodlands from sea-level to 1,000 metres[12][13]. The best specimens are found in the deep soil of cool wet coastal forests[9].

Medicinal: The plant has been used in sweat baths for treating rheumatism and arthritis[14].

An infusion of the branch tips has been used as a wash for sores and swellings[14].

A poultice of the crushed leaves has been applied to sores[14].

The soft bark has been used as a cover for poultices[14].

Usage: Plants can be grown as a tall hedge[5] They are very tolerant of clipping so long as this does not extend into the brown barked wood since trees cannot regenerate from this[5]. Any trimming should be done in the summer[5].

The fibre of the inner bark is fine and soft, it is pounded and spun then used for making blankets, clothing, capes, mats etc[15][9][14]. Torn into pieces, it can be used as bandages or for washing babies[9].

The finely shredded inner bark can be used as a tinder[14].

Wood - hard, very durable, fragrant with an agreeable resinous odour, close grained, has low-shrinkage, is somewhat brittle, but does not splinter. Easily worked, it is used for carving, cabinet work, making boats, implements etc[3][16][17][13][15][18][9].

Also Known As: Cupressus nootkatensis. Thuyopsis borealis.
