Cupressus (= Hesperocyparis) arizonica, Arizona Cypress

Arizona Cypress is a handsome pyramid-shaped conifer that grows in the southwestern United States. It can reach a height of 70 feet and 15 to 20 feet wide. Cupressus arizonica (= Hesperocyparis arizonica) Arizona Cypress is a gymnosperm and has now flowers. The seed cones are nearly globose, blue or blue-gray and remain on the branches several years after the seeds have fallen. Cupressus arizonica (= Hesperocyparis arizonica) Arizona Cypress occurs in a variety of habitats including canyon riparian associations which include a few typically riparian species such as Arizona Sycamore (Platanus wrightii), Fremont Cottonwood, (Populus fremontii) and Arizona Walnut (Juglans major). Cupressus arizonica (= Hesperocyparis arizonica) Arizona Cypress is drought-tolerant, aromatic and often very attractive. It is cultivated in the southern United States as an ornamental and for windbreaks. In some parts of the southwest it is grown as a Christmas tree. This species has also been used in the past locally for rough construction and fencepost. Cupressus arizonica (= Hesperocyparis arizonica)

Comments: Arizona Cypress is drought-tolerant, aromatic and often very attractive. It is cultivated in the southern United States as an ornamental and for windbreaks. In some parts of the southwest it is grown as a Christmas tree. This species has also been used in the past locally for rough construction and fencepost. Bark texture is not a clear characteristic to distinguish geographic varieties as within the species as a whole there is complete inter gradation between bark types.

Type species of Cupressus arizonica is from near Clifton, Arizona; (Green in 1880).

Arizona Cypress occurs in a variety of habitats. One such habitat is canyon riparian associations which include a few typically riparian species such as Arizona Sycamore (Platanus wrightii), Fremont Cottonwood, (Populus fremontii) and Arizona Walnut (Juglans major).
