Japanese Cryptomeria is a medium to large size tree in its native land where it is an important timber and landscape tree. This species appears to be suitable for use in the eastern third of our region. Trees are pyramidal to conical in outline with older limbs retained for extended periods of time. Needles are singular, densely surrounding the twigs, arch forward on the twig, and are a dark lustrous green color. The bark on older trees is a handsome shaggy reddish brown. Although the ultimate range of adaptability is not fully known in our region, this species is worthy of further testing.
