Thuja plicata (Western red cedar). This is a common tree in the Northwest, with dark green lacy, scale-like leaves, turning bonze in the winter. It is used extensively as a source of timber, and grows well in cool moist soils and will need partial shade in hot inland areas.
They will tolerate the cold, and will grow well in well drained soil, they prefer full sun and dislike dry conditions. Prune in late summer. Once it is established (in native areas), it will need no water.
Specimen, hedging. Year-round interest.
Timber greenhouses are often made from Western red cedar.
