Monterey cypresses (Cupressus macrocarpa) planted in Melbourne, Australia.

Cypress is the name applied to many plants in the cypress family Cupressaceae, which is a conifer of northern temperate regions. Most cypress species are trees, while a few are shrubs.

Cupressus sempervirens is famous for its longevity, and has been a popular garden plant for thousands of years.

The word cypress is derived from Old Frenchcipres, which was imported from Latincypressus the latinisation of the Greek κυπάρισσος (kyparissos).[2][3]

The Cupressaceae family also contains 13–16 other genera (not listed above) that do not bear cypress in their common names.

The word cypress is also used as a descriptor for the angiosperm vine in the bindweed family Convolvulaceae, known as the cypress vine (Ipomoea quamoclit).

The plant called "summer cypress" is Bassia scoparia (Amaranthaceae).
