Eastern Red Cedar
Eastern red cedar, commonly called the red cedar, eastern juniper, pencil cedar, and red juniper, is a species of dense, slow-growing conifers that belong to the genus Juniperus of the family Cupressaceae. Known for its graceful appearance and being incredibly strong for its small to medium size, the red cedar is found in the eastern and northern states of America. The two varieties of eastern red cedar include Juniperus virginiana var. virginiana or eastern juniper (distinguished by larger cones, acute scale leaves at the apex, and reddish brown bark) and Juniperus virginiana var. silicicola or southern juniper (characterized by smaller cones, blunt scale leaves at the apex, and orange-brown bark).

- In several places, the eastern red cedar is regarded as an invasive species. Since it does not tolerate fire, it was earlier controlled by occasional forest fires.
- The red cedar originated during the ancient era when aboriginal Americans existed. Fossil evidence has shown that it occurred in large parts of the continent.
- The pollen of eastern red cedar is an allergen, but less potent than that of Ashe juniper. Contact with the red cedar’s wood or leaves can cause mild skin irritations in some people.
