Dense, dark, wonderfully fragrant evergreen foliage from the ground up never needs shearing or pruning. An ideal choice for a privacy screen, it is easy to grow, and very long-lived, with good deer, pest, and disease resistance. Best if grown in sun but will tolerate light shade. Reaches 30 to 50 feet tall, 8 to 10 feet wide in just 10 years. Grows 3 feet or more each year, topping out at 50 feet tall. Stands up to wind, heavy ice and snow loads, and temperatures to -20° F. Deer, bagworms, and other pests and insects leave it alone. Adapts to most any soil. Wonderful "piney" fragrance. Great alternative to Hemlock in the North, Leyland Cypress in the South. Stays green year-round and doesn't mind heat and drought. Branches right down to the ground and can be sheared to any shape. Thrives in full sun to light shade.
