CHAMAECYPARIS (FALSE CYPRESS)
With the exception of yew, conifers are not usually closely clipped, since they act primarily as screens and wind-breaks. Juniper and spruce are among the plants used in this way, and they provide a wide range of foliage colour.

Chamaecyparis lawsoniana (syn. Cupressus lawsoniana). As a hedge, Lawson’s cypress plants are restricted to between 10 and 15 ft. Plant in September or March, 1-1/2 to 2 ft. apart. Trim them once they are established, if necessary as soon as June, but do not clip closely. Cones, which are glaucous at first and later brown, are produced only on plants that are allowed to grow naturally. For screens up to 50 ft., plant about 5 ft. apart and remove alternate plants when the branches touch.
C. l. allumii has glaucous blue-green foliage and an attractive pyramidal habit. Tends to tolerate wind better than the type.
C. l. Green Hedger has very attractive mid-green foliage,
C. l. lutea is a golden form, also tolerant of wind.
