Cuprocyparis leylandii, commonly called Leyland cypress, is a bi-generic fertile hybrid between Monterey cypress (Cupressus macrocarpa) and Nootka false cypress (Chamaecyparis nootkatensis). It is a fast-growing (18-36” per year in early years) evergreen conifer with a dense, broad-columnar to a narrow-pyramidal habit that typically grows as a tree to 60-70’ (less frequently to 100’) tall in landscapes unless pruned otherwise. 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. Features flattened sprays of gray-green foliage on slender upright branches and dark brown fruiting cones (to 3/4” across), each with 8 scales. Scaly, reddish-brown bark.
