description_en: 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.
