Habitat And Range

Arborvitae is found in wet ground and along streams from Canada south to North Carolina and Tennessee and west to Minnesota and Manitoba.


This evergreen tree, which reaches a height of 70 feet and a trunk diameter of 5 feet, needs no special description, as few people within its range are unfamiliar with its flat scalelike leaves and small cones from one-third to one-half inch long. The old bark is shed each year in long, ragged strips.

Part Used

The leaves and branchlets.
