distribution_en:

description_en: Genus of about 24 species of evergreen, monoecious, coniferous trees from the N. hemisphere, found in dry, open hillside forest. The paired, overlapping, forward-pointing, scale-like leaves vary from rounded to pointed at the tips. The mature bark often breaks off into curling or rounded scales. Small, spherical to ovoid female cones, to 4cm (1 1/2in) long, ripen in the second year but usually persist on the tree, and have 5-20 seeds per scale. Ovoid green male cones, 2-3mm (1/16-1/8in) long, are borne at the shoot tips. Cypresses tolerate dry conditions and are excellent specimen trees. C. macrocarpa may be used as a hedge or screen. In frost-prone areas, grow C. torulosa ‘Cashmeriana’ in a cool greenhouse or conservatory.

hardiness_en: Fully hardy to half hardy.

cultivation_en:

propagation_en: Sow seed in a seedbed, or in containers in a cold frame, in spring. Root semi-ripe cuttings in late summer.

pests_en: May be affected by honey fungus. Coryneum canker may cause the death of twigs and ultimately entire trees. Aphids may cause dieback.
