Botanical Name

Plant Common Name

Arizona Cypress, Carolina Sapphire Arizona Cypress

General Description

Carolina Sapphire Arizona cypress is a broad, upright evergreen conifer tree with branches of soft blue-green to steel blue foliage. Native to the southwestern United States, the undersides of the scaley leaves are covered in white resin glands. Small, prickled, round cones add seasonal interest as does the smooth reddish bark. This cultivar was selected and released by Clemson University in South Carolina.

A sunny, dry location is needed to grow Arizona cypress with soils that are well-drained. Amend clay soils with grit or organic matter and avoid highly alkaline pH ground. 'Carolina Sapphire' will grow into a low-maintenance tall hedge or windbreak or an attractive specimen tree. It may be favored as a Christmas tree in certain regions, but is not a long lived tree in climates with heavy, wet soils or lots of humidity year round with little air circulation.
