Thuja occidentalis (Northern White Cedar)

This evergreen tree is native to eastern Canada and much of the north-central and north-eastern parts of the United States. It has been in the ornamental plant trade in Australia since 1843 and has not become naturalised in that time. There is a small degree of similarity in climate between its native range and parts of NSW. There are no records of the species being noted as invasive anywhere in the world. Thuja occidentalis produces copious amounts of wind-dispersed seed and can also reproduce by layering. Northern White Cedar has dense, evergreen aromatic yellow-green foliage on fan shaped branchlets. It produces small cones with diamond shaped patterns.
