Uses

Edible uses

There are no edible uses listed for Chamaecyparis lawsoniana.

Material uses

Plants can be grown as a tall hedge[1][2][3] They are very tolerant of clipping so long as this does not extend into the brown barked wood since trees cannot regenerate from this[3]. Any trimming should be done in the summer[3].

Certain dwarf forms can be used for ground cover, the cultivars 'Knowefieldensis', 'Nidiformis' and 'Tamariscifolia' have been recommended[4]. The branches have been used to make brooms[5].

Wood - very close-grained, hard, strong, durable, easily worked, light, abounding in fragrant resin, acid resistant. One of the world's finest timbers, it is widely used for flooring, fencing, making boats etc[6][7][8][9]. It is now in short supply due to over-harvesting without replanting[3].

Propagation

Seed - sow March/April in a seedbed outdoors[10]. 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[11]. 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[12][13][3]. Difficult, it may be best done in late winter to early spring[11].

Cultivation

Succeeds in most soils and situations, but prefers a moist deep loamy soil and a sheltered position[12][13]. Grows well in heavy clay soils. Survives on dry alkaline soils[3]. Growth of trees is hardly affected by a lack of phosphate in the soil. Plants are moderately shade tolerant, especially when young[14][3]. Plants are tolerant of atmospheric pollution according to one report[3], whilst another says that they do not do well in a polluted atmosphere[12]. A fairly wind tolerant plant, but it does not like severe maritime exposure[2]. Plants are susceptible to wind burn and recover variably[2].

This species is hardy to about -25°c[3]. A fairly long-lived tree in the wild with specimens 500 - 600 years old[15]. It is a very valuable timber tree in N. America and it is sometimes cultivated as a forestry tree in Britain, where it occasionally self-sows[12][13]. It establishes well and grows quickly. New shoots can make 1 metre in a year but trees rarely maintain that rate and 30cm is nearer the average[16]. New growth starts very slowly in April, speeds up in June and ceases in September[16]. A very uniform species in the wild[3], in cultivation it is polymorphic and there are many named varieties[12][16][3]. The crushed foliage has a pungent smell[17]. Favoured by many birds for roosting, providing high cover and especially for nesting, large specimens of this tree help to attract songbirds to the garden[3].

Trees are notably susceptible to honey fungus[3].
