- Description
-
Japanese cedar is a woody, needled evergreen tree in the Cupressaceae (cypress) family that is native to central and south Japan and China. It may reach 50 to 70 feet tall and 20 to 30 feet wide with a conical to pyramidal shape.The genus name comes from the Greek krypto, meaning to hide, and meris, meaning a part in reference to the concealed position of the reproductive organs.
Japanese cedar prefers rich, moist, well-drained, acidic soils but is adaptable to other soil types. It grows well in dappled sunlight, full sun, or partial shade.The reddish-brown exfoliating bark can be quite attractive, and the wood is highly valued for building many things. This cedar is resistant to damage by deer and is slightly salt tolerant. It is generally considered low maintenance.
The soft, graceful habit of the Japanese cedar makes it ideal as a specimen tree in a lawn or naturalized area. It is a great alternative to the leyland cypress for screening purposes. Shorter cultivars are available.
