- Description
-
Atlantic white cedar is a woody, needled evergreen tree in the Cupressaceae (cypress) family that may grow 60 to 80 feet tall and 30 to 40 feet wide with a conical form. It is native to the eastern United States. The genus name derives from the Greek word chamai, for dwarf or low to the ground, and kyparissos, for cypress.
Atlantic white cedar prefers sandy, peaty, moist to wet, acidic soil in full sun to part shade and tends to grow on a small mound, with water pooling in the depression surrounding it. In North Carolina it is found in the coastal plain along bogs, streams, swamps, and other wet sites. It tends to be the dominant species in wet forests. Propagate this plant by seed or stem cutting.
Use this plant in wet areas with poor drainage, or along ponds, streams, or boggy sites. Include it in butterfly, pollinator, or rain gardens. It provides cover for wildlife and is a larval host plant for butterflies. Planted in small groups it makes an effective privacy screen.
Insects, Diseases, or Other Plant Problems: It has some susceptibility to juniper blight, root rot, and certain insect pests such as bagworms. See Clemson's publication on root rot. This tree is frequently damaged by deer in the winter.
