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.
Prized for the ability to grow 3 to 4 feet per year for the first years of life, the Leyland Cypress is capable of heights in the 100-foot range and spreads to 20 feet easily. The concern for this soft needled, blue-green giant is typically how to control, rather than induce, rapid growth.
