Notes: Leyland Cypress is a popular fast-growing evergreen tree often used for privacy screens, windbreaks, and hedges. It is prized for its rapid growth, dense foliage, and ability to form tall, uniform screens, but it can suffer from disease issues in humid, rainy climates and may require occasional pruning to maintain shape.
