A Leyland cypress tree (Cupressocyparis leylandii) is a fast-growing, evergreen conifer known for its dense, feathery foliage, columnar shape, and ability to tolerate heavy pruning, making it a popular choice for privacy screens and hedges; it can reach heights of 50-70 feet tall with a rapid growth rate of several feet per year, but requires regular maintenance to manage its size due to its quick growth potential; this tree is a hybrid created from a cross between the Monterey cypress and the Nootka cypress, and is often planted in large landscapes due to its potential to outgrow smaller spaces if not regularly trimmed. 

Grows 3'-4' per year.
