Chamaecyparis lawsoniana (Lawson cypress). This is a tall conical tree with pendulous branches native to the humid coastal forests of northwestern USA. Foliage is an attractive bluish to deep green. Planted trees can reach 40 m tall with trunks approx 1.2 m in diameter. It is the parent of many cultivars of any other conifer species. The fast growing bigger varieties will remove nutrients and moisture from the soil around their base, block out sunlight and may well irritate neighbours if planted as boundary hedges.
They are tolerant of chalky soils but grow best in moist but well drained neutral to slightly acid soil. If the conifer produces more than one leader, to maintain the general conical habit remove all but one leader. To restrict the height of the plant, the leader can be cut back.
