Hesperocyparis macrocarpa: Monterey Cypress

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein and Deborah R. Hilbert

Introduction

Monterey cypress thrive near the sea on the west coast of the United States, where it is native to the Monterey Bay, California, area. It has a high wind tolerance, becoming increasingly more attractive under heavy wind conditions. Narrow and pyramid-shaped when young, monterey cypress spreads with age, and can become 70 to 90 feet in height. It is one of the major trees planted to hold the sands in Golden Gate Park, San Francisco, but unfortunately many are dying. The plant is only grown in the western states.
