Found growing in the forests of Western North America, the western red cedar, Thuja plicata, makes a useful hedging plant. Allowed to grow naturally, it makes a tall, conical-shaped tree that can reach up to 35m high. The scale-like leaves are mid- to dark green.
Plant Thuja plicata in a sunny spot in moist but well-drained soil. Trim hedges twice a year in spring and late summer, but do check for nesting birds before hand and leave pruning until autumn if you think birds may be using the hedge. Be careful if you have sensitive skin as the foliage may aggrevate skin allergies.
