Cupressocyparis × leylandii, commonly known as Leyland Cypress, is a fast-growing, evergreen conifer often used for privacy screens and windbreaks. This sterile hybrid between Monterey Cypress (Cupressus macrocarpa) and Nootka Cypress (Chamaecyparis nootkatensis) can grow 3 to 4 feet per year, reaching heights of 40 to 60 feet or more. With soft, feathery green foliage and a dense, upright habit, it provides year-round screening and is commonly planted along property lines. While popular for its speed and form, Leyland Cypress is non-native and offers minimal support for wildlife.

Why choose Leyland Cypress:

• Rapid growth: Ideal for creating quick privacy or large evergreen hedges

• Dense form: Naturally thick foliage provides year-round screening and wind protection

• Adaptable: Tolerates a range of soils and is widely used in suburban and urban landscapes

Cultivating tips:

• Sun exposure: Requires full sun for optimal density and health

• Soil needs: Prefers well-drained soil; avoid poorly drained, wet locations

• Maintenance: Prune to control size; allow space for mature height and width

Designs for your garden:

• Privacy screens: A popular choice for fast evergreen barriers

• Windbreaks: Effective for reducing wind in open or exposed landscapes

• Property borders: Offers a clean, green backdrop for other landscape elements

Ecological considerations:

• Non-native hybrid: Provides little habitat or food value for native wildlife

• Disease susceptibility: Prone to canker and root rot in overly wet soils

• Best used with natives: Consider planting with native evergreens for improved biodiversity
