Atlantic white cedar (Chamaecyparis thyoides) belongs to the Cupressaceae (the Cypress family). It is a tall evergreen tree that is native to the Atlantic coast of North America. This tree grows in forested wetlands and usually to 20-28 m tall. The bark is smooth on juveniles, but mature trees have deep ridges and bark as thick as 5 cm. The leaves are scale-like, 2-4 mm long, and produced in opposite decussate pairs on somewhat flattened shoots. The seed cones are globose, 4-9 mm diameter, with 6-10 scales, green or purple, maturing to brown in 5-7 months after pollination.
