Cupressus arizonica var. arizonica: Arizona Cypress1

Edward F. Gilman and Dennis G. Watson 2


This rapidly-growing North American native evergreen reaches 30 to 40 feet in height with a 15 to 25-foot-spread. It is referred to as Cupressus glabra by some botanists. The green foliage has a silver/gray shimmer and the branches are more open than most other species of juniper. The inconspicuous flowers are followed by small, 1-inch cones which persist on the tree. The peeling brown bark becomes gray with age. Arizona cypress is often used as a specimen or windbreak planting and is a common sight in west Texas and the southern High Plains where it tolerates the hot, dry conditions with ease.

Use and Management

It can be found growing with a single trunk or in clumps. It is probably best used in landscapes which are not irrigated since it is susceptible to juniper blight. Many locations in the eastern part of the country are too humid to successfully grow this tree. It is most often found in the west and in the drier parts of Texas and Oklahoma.

Arizona cypress should be grown in full sun on well-drained soil. Although it will tolerate clay soil, the shallow roots will not gain as secure an anchor as they might in other soils and the tree may, as a result, topple over during wind and rainstorms.

Cultivars of Cupressus arizonica include: 'Compacta'—low, conical; 'Gareei'—silver blue foliage; 'Glauca'—leaves silvery-grey; 'Greenwood'—medium silver/grey/green; 'Oblonga'—horizontal branches, producing oblong effect, leaves grey/green; 'Verhalenii'—leaves bright glaucous-blue, softer and more graceful than wild forms; 'Watersii'—narrowly pyramidal, compact.

Propagation is by seed or grafting.




Juniper blight, especially in cool, humid regions.

A stem canker has devastated large numbers of trees in various parts of the country.
