Cupressocyparis leylandii 'Leighton Green', commonly known as Leighton Green Leyland Cypress, is a fast-growing evergreen conifer prized for its dense, upright growth habit and vibrant green foliage. This cultivar is a popular choice for hedges, windbreaks, privacy screens, and ornamental plantings in Australian landscapes.

Height and Width

• Height: Typically grows to a height of 15 to 20 meters or more when mature.
• Width: Spreads out to a width of about 4 to 6 meters.

Soil Type

• Soil Preference: Leighton Green Leyland Cypress prefers well-drained soil with a loamy or sandy texture. It can tolerate a range of soil pH levels, from slightly acidic to slightly alkaline, but requires good drainage to prevent waterlogging.

Plant Description

• Foliage: The plant features dense, feathery foliage that is bright green in color, providing year-round interest and privacy screening. The foliage consists of scale-like leaves arranged in flattened sprays along the branches.
• Growth Habit: Leighton Green Leyland Cypress has a fast-growing, pyramidal growth habit with a dense, upright form. It typically maintains a uniform shape without the need for extensive pruning, making it an excellent choice for formal hedges and screens.

Flower and Fruit Description

• Flowers: Leyland Cypress produces small, inconspicuous flowers in spring, but they are not particularly showy or ornamental.
• Fruit: The plant may produce small, round cones containing seeds, but they are generally inconspicuous and do not contribute significantly to its ornamental value.

Cultivation and Care

• Watering: Provide regular watering during the establishment period to ensure proper root development. Once established, Leyland Cypress is moderately drought-tolerant but benefits from occasional deep watering during dry periods.
• Sunlight: Prefers full sun to partial shade. It thrives in bright, sunny conditions and can tolerate some shade, but full sun exposure promotes optimal growth and density.
• Temperature: Leyland Cypress is tolerant of a wide range of temperatures and is suitable for growing in most regions of Australia. It can withstand heat, drought, and moderate frost once established.
• Pruning: Prune as needed to maintain shape, remove dead or diseased branches, and promote airflow within the canopy. Leyland Cypress responds well to regular pruning and can be shaped into formal hedges or screens.
• Fertilising: Apply a balanced, slow-release fertiliser formulated for evergreen trees and shrubs in spring to provide essential nutrients for healthy growth.

Additional Notes

• Pests and Diseases: Leyland Cypress is generally resistant to pests and diseases, but it may be susceptible to cypress aphids, spider mites, and fungal diseases such as canker and root rot in certain conditions. Monitor regularly and treat promptly if issues arise.
• Uses: Ideal for use as a formal hedge, windbreak, privacy screen, or specimen planting in gardens, parks, and landscapes. Leyland Cypress provides rapid growth, dense foliage, and year-round greenery, making it a valuable addition to Australian landscapes.
