説明（英語）: Genus of 7 species of monoecious, evergreen, coniferous trees from forest in Taiwan, Japan, and North America. They have flattened sprays of scale-like, overlapping adult leaves, 1-5mm (1/16-1/4in) long, and larger, ovate to linear juvenile leaves, 2-8mm (1/16-3/8in) long. The spherical or angular female cones have 2, occasionally 3-5 seeds on each shield-like scale, and most ripen in the first autumn. The spherical or ovoid male cones, usually 1-5mm (1/16-1/4in) long, are borne in spring. Cypresses are used as specimen trees and for hedging; they have given rise to a vast number of cultivars, many dwarf or slow-growing and suitable for rock gardens or bonsai. Contact with the foliage may aggravate skin allergies.

耐寒性（英語）: Fully hardy.
