Cryptomeria: Japanese Cedar
Cryptomeria is the national tree of Japan. It can be found planted at many sacred sites and is also planted on a large scale as a forest tree. Only one species exists, Cryptomeria japonica. It grows fast into a very large lofty, pyramidal or conical evergreen tree, with red-brown bark which peels in vertical strips. The wood is scented, waterproof, lightweight and strong, so it is used for all types of construction in Japan.
Though only one species of Cryptomeria exists, many ornamental varieties are in cultivation and are very suitable to Northwest landscapes. Portland Nursery carries a full selection of miniature to full-size forms to fit perfectly into the any garden site.
Cryptomerias are especially interesting because they offer a wide range of color and texture choices. During winter several varieties have foliage that changes color from green to bronze or burgundy. Some varieties are soft and plume-like foliage while others have branches and leaves that resemble dreadlocks or ringlets. Cryptomerias lend year round interest and are an excellent addition to the Northwest garden.
