A hybrid cross between Monterey cypress (Cupressus macrocarpa) and nootka false cypress (Chamaecyparis nootkatensis). It is a fast-growing evergreen conifer (18 to 36 inches per year in early years) with a dense, broad-columnar to narrow-pyramidal habit. It typically grows as a tree to 60 to 70 feet tall unless it is kept pruned as a hedge or specimen shrub. From its nootka false cypress parent, it inherits its habit, foliage, and winter hardiness, and from its Monterey cypress parent, it inherits its branching pattern and rapid growth. Leyland cypress has flattened sprays of gray-green foliage on slender upright branches, and dark brown fruiting cones. The scaly bark is reddish-brown.
