Plant description

Cupressocyparis leylandii 'Leighton Green' is a large evergreen tree. It is a very fast and dense growing, very large conifer. It is used for hedges, screens and wind breaks, but care should be taken with planting, as they can grow to 35 metres tall. It is a shallow rooted plant. It can be trimmed to a large hedge, to around 3-5 metres tall. It likes a cool to temperate climate. Does well on a wide range of soils. Tolerates frost and salt spray, as well as air pollution.

This tree is also known as Cupressus x leylandii. It is a hybrid of the Monterey cypress and the Alaskan cypress, and is one of the fastest growing conifers.

This tree is susceptible to cypress canker, a serious fungal disease which can kill the plant. Good plant nutrition will help to keep the tree healthy. The fungus interferes with sap conduction, causing limb browning and die back. Treat with a fungicide, or remove and plant a less susceptible species.
