- Description
-
Atlantic White Cedar is an evergreen tree in the cypress family that may grow 60 to 80 feet tall with a diameter of 2 ft. The foliage is scale-like and green to blue/green in color. The bark is fibrous with intersected flat ridges, which sometimes spiral along the stem. In NC it is found in the coastal plain along bogs, streams, swamps and other wet sites. They tend to be the dominant species in wet forests.
The Atlantic White Cedar prefers sandy, peaty, moist to wet soil in full sun to part shade and tends to grow on small mounds, with water pooling in the depressions surrounding them. Use this plant in wet areas with poor drainage along ponds, streams or boggy sites.
Insects, Diseases, or Other Plant Problems: With the Atlantic White Cedar there are no serious insect or disease problems. It does have some susceptibility to juniper blight, root rot and certain insect pests such as bagworms. This tree is frequently damaged by white tailed deer.
