Cupressus sempervirens: Italian Cypress1

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, Andrew K. Koeser, Deborah R. Hilbert, and Drew C. McLean2

Introduction

With its narrow columnar habit of growth, this evergreen forms tall, dark green columns 40 to 60 feet in height in the western United States but are often much shorter. Trees are normally no more than three feet wide. The scale-like leaves lend a very fine texture to any setting. Planted 3 feet apart, they make a dense screen. Italian cypress is often used for framing, as a strong accent around large buildings, or in the formal landscape but does not lend itself well to many home landscapes. It quickly grows much too tall for most residential landscapes, looking much like a green telephone pole.

Use and Management

Growing in full sun on various well-drained soils, Italian cypress should be planted in a well-prepared site and watered periodically until well-established. Italian cypress should not be pruned. It is very susceptible to mites and trees are often infested.

Many cultivars are available; 'Glauca'—blue-green foliage and tight columnar form; 'Stricta'—very popular; `'Horizontalis'—horizontally-spreading branches.

Propagation is by cuttings or layering.

Pests

Bagworms are occasionally a problem for Italian cypress. Mites are often a problem.

Diseases

Root rot can be a problem for Italian cypress in poorly-drained soil. Canker is a devastating disease that has killed many trees in California.
