Monterey cypress was introduced to the British Isles in 1838 and has an extremely restricted natural range; Cypress point and Lobos point in Monterey county, California. It's widely planted in parks and gardens and when mature it can make an imposing specimen. Around the late 1800's Monterey cypress and Nootka cypress (Cupressus nootkatensis) hybridised to produce Leylandii (Cupressus x leylandii), now almost ubiquitous across the British Isles.
