原生地・分布（英語）: N.temp. and S. to C.America

説明（英語）: Genus of approximately 120 species of monoecious, evergreen, coniferous trees or shrubs, widely distributed in forests of the N. hemisphere from the Arctic Circle to Central America, Europe, N. Africa, and S.E. Asia. The bark is often fissured, and in some species is divided into irregular, plate-like sections. Pines have small bundles of 2-5, rarely 1 or 6-8, needle-like, light to dark green or yellow-green to bluish or grey-green leaves, which usually persist for 2-4 years, sometimes for longer. The winter buds are usually cylindrical or ovoid, and often resinous. Female cones take 2, or occasionally 3 years to ripen; the seeds are winged in most species. Male cones are yellow and catkin-like, clustered at the shoot bases. Pines are useful as specimen trees, and for shelter and windbreaks; some cultivars and slow-growing species are suitable for a rock garden.

耐寒性（英語）: Fully hardy to frost hardy.

栽培（英語）:

繁殖（英語）: Sow seed of species in containers in a cold frame in spring. Graft cultivars in late winter.

病害虫（英語）: Prone to adelgids, aphids, sawfly larvae, honey fungus, pine shoot moth, and various needle cast diseases. Some 5-needled pines are susceptible to white pine blister rust.
