Suitable for U.S. Department of Agriculture plant hardiness zones 6 through 9, Leyland cypress is a naturally fast grower, growing 20 to 30 feet tall in the first 10 years, and eventually reaching over 50 feet tall and 20 feet wide.
Leyland cypress trees grow as much as 4 feet per year when they are young. So a tree that's 4 feet tall when purchased could reach 12 feet within two years. A tree that's 2 feet tall at planting time will need at least 30 months to reach 12 feet in height.
