Hardy in zones three through eight, the pyramidal arborvitae prefers full sun to thrive, but will work with partial shade as well. They will perform best in an area with high atmospheric moisture content.
Pyramidal arborvitaes make excellent hedge plants, as they grow fairly fast and have dense foliage that make good wind blocks for more delicate plants.
They are also much easier to propagate than are most other plants.
Propagation can be done best from cuttings.
It is possible to tear a pyramidal arborvitae apart and make literally hundreds of cuttings that will grow into full sized plants.
Pyramidal arborvitae should be pruned early in the season, prior to new growth. This is often not needed, however, because the plants often grow naturally into a perfect pyramidal shape.
If the winter is especially cold, the foliage of a pyramidal arborvitae will turn yellow-brown. The lush foliage of the pyramidal arborvitae makes it an attractive plant year round.
