Northern white cedar, botanically named thuja occidentalis, is an evergreen coniferous tree of the cypress family.
Also known as eastern white-cedar or arborvitae, it is native to much of eastern Canada and the north-central and northeastern United States.
The plant grows naturally in moist forests and is especially abundant in coniferous swamps, where it out-competes other larger, faster-growing trees.
Leaves are scale-like, 3-5 mm long, and form foliage in flat sprays.
The bark is wrinkled, thin, longitudinally peeling, and reddish brown.
