Botanical description
Platycladus orientalis is an evergreen coniferous tree or shrub, native to northeastern China and Korea. It is a slow-growing plant, typically reaching heights of 50-65 feet. The foliage consists of scale-like leaves arranged in flattened sprays. Cones are small, globose, and bluish-green, maturing to brown. The bark is reddish-brown and peels in thin strips. It is generally pyramidal or columnar in shape.
Companion planting
Platycladus orientalis is generally compatible with a wide range of plants. Its dense foliage can provide shelter for smaller plants. Avoid planting near plants that require very acidic soil conditions.
Propagation methods
Propagation can be achieved through seeds, cuttings, or layering. Seed propagation requires stratification to break dormancy. Cuttings are best taken from semi-hardwood in late summer. Layering can also be successful, but it is a slower method.
History and traditions
In traditional Chinese medicine, Platycladus orientalis has been used for centuries to treat various ailments, including bleeding, insomnia, and coughs. It is also considered a symbol of longevity and is often planted near temples and homes. The wood has been used in construction and for making furniture.
Usage calendar
Seeds mature in the fall. Cuttings are best taken in late summer. Planting can be done in spring or fall. Pruning is typically done in late winter or early spring to remove dead or damaged branches.
