Cupressus × leylandii / Leyland cypress
Cupressus × leylandii, is commonly known as the Leyland cypress, commonly seen described in other studies as × Cupressocyparis leylandii, Callitropsis × leylandii, or often simply as Leylandii, is a fast-growing coniferous evergreen tree much used in horticulture, primarily for hedges and screens. Even on sites of relatively poor culture, plants have been known to grow to heights of 50 feet (15 m) in 15 years. Their rapid, thick growth means they are sometimes used to enforce privacy, but such use can result in disputes with neighbors whose own property becomes overshadowed. It is a hybrid of two new-world cypresses, namely C. nootkatensis and C. macrocarpa.
