See List of Pinus species for complete taxonomy to species level. See list of pines by region for list of species by geographic distribution.

Pinus is the sole genus in the subfamily Pinoideae. The Plant List compiled by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts species names of pines as current, together with 35 unresolved species and many more synonyms. The smallest are Siberian dwarf pine and Potosi pinyon , and the tallest is an Pines are long lived and typically reach ages of —1, years, some even more. The longest-lived is the Great Basin bristlecone pine , Pinus longaeva.

One individual of this species, dubbed " Methuselah ", is one of the world's oldest living organisms at around 4, years old. This tree can be found in the White Mountains of California. It was discovered in a grove beneath Wheeler Peak and it is now known as " Prometheus " after the Greek immortal. The bark of most pines is thick and scaly, but some species have thin, flaky bark. The branches are produced in regular "pseudo whorls", actually a very tight spiral but appearing like a ring of branches arising from the same point. Many pines are uninodal, producing just one such whorl of branches each year, from buds at the tip of the year's new shoot , but others are multinodal, producing two or more whorls of branches per year.

The spiral growth of branches, needles, and cone scales may be arranged in Fibonacci number ratios. These "candles" offer foresters a means to evaluate fertility of the soil and vigour of the trees. Pines are mostly monoecious , having the male and female cones on the same tree, though a few species are sub-dioecious , with individuals predominantly, but not wholly, single-sex.

The male cones are small, typically 1—5 cm long, and only present for a short period usually in spring, though autumn in a few pines , falling as soon as they have shed their pollen. The female cones take 1. At maturity the female cones are 3—60 cm long. Each cone has numerous spirally arranged scales, with two seeds on each fertile scale; the scales at the base and tip of the cone are small and sterile, without seeds.

The seeds are mostly small and winged, and are anemophilous wind-dispersed , but some are larger and have only a vestigial wing, and are bird -dispersed see below. At maturity, the cones usually open to release the seeds, but in some of the bird-dispersed species e. In others, the seeds are stored in closed "serotinous" cones for many years until an environmental cue triggers the cones to open, releasing the seeds. The most common form of serotiny is pyriscence, in which a resin binds the cones shut until melted by a forest fire. The genus is divided into two subgenera, which can be distinguished by cone, seed, and leaf characters:.

Pines are native to the Northern Hemisphere , and in a few parts of the tropics in the Southern Hemisphere. Most regions of the Northern Hemisphere see List of pines by region host some native species of pines. They often occur in mountainous areas with favorable soils and at least some water. Various species have been introduced to temperate and subtropical regions of both hemispheres, where they are grown as timber or cultivated as ornamental plants in parks and gardens. A number of such introduced species have become naturalized, and some species are considered invasive in some areas [7] and threaten native ecosystems.

Pines grow well in acid soils, some also on calcareous soils; most require good soil drainage, preferring sandy soils, but a few e.

A few are able to sprout after forest fires e. Some species of pines e. Several species are adapted to extreme conditions imposed by elevation and latitude e. Siberian dwarf pine, mountain pine , whitebark pine, and the bristlecone pines. The pinyon pines and a number of others, notably Turkish pine and gray pine , are particularly well adapted to growth in hot, dry semidesert climates. The seeds are commonly eaten by birds, such as grouse, crossbills, jays, nuthatches, siskins, and woodpeckers, and by squirrels. Some birds, notably the spotted nutcracker , Clark's nutcracker , and pinyon jay , are of importance in distributing pine seeds to new areas.

Pine needles are sometimes eaten by some Lepidoptera butterfly and moth species see list of Lepidoptera that feed on pines , the Symphytan species pine sawfly , and goats. Pine pollen may play an important role in the functioning of detrital food webs. Pines are among the most commercially important tree species valued for their timber and wood pulp throughout the world. Commercial pines are grown in plantations for timber that is denser and therefore more durable than spruce Picea. Pine wood is widely used in high-value carpentry items such as furniture, window frames, panelling, floors, and roofing, and the resin of some species is an important source of turpentine.

Because pines have no insect- or decay-resistant qualities after logging, they are generally recommended for construction purposes as indoor use only indoor drywall framing, for example. Left outside, pine wood can be expected to last no more than 12—18 months depending on the local climate. Many pine species make attractive ornamental plantings for parks and larger gardens with a variety of dwarf cultivars being suitable for smaller spaces.

Pines are also commercially grown and harvested for Christmas trees. Pine cones, the largest and most durable of all conifer cones , are craft favorites. Pine boughs, appreciated especially in wintertime for their pleasant smell and greenery, are popularly cut for decorations. Civil War , the needles of the longleaf pine "Georgia pine" were widely employed in this. Pine needles are also versatile and have been used by Latvian designer Tamara Orjola to create different biodegradable products including paper, furniture, textiles and dye.

Pine needles serve as food for various Lepidoptera. See List of Lepidoptera that feed on pines. Several species are attacked by nematodes, causing pine wilt disease , which can kill some quickly. When grown for sawing timber, pine plantations can be harvested after 30 years, with some stands being allowed to grow up to 50 as the wood value increases more quickly as the trees age. Imperfect trees such as those with bent trunks or forks, smaller trees, or diseased trees are removed in a "thinning" operation every 5—10 years.

Thinning allows the best trees to grow much faster, because it prevents weaker trees from competing for sunlight, water, and nutrients. Young trees removed during thinning are used for pulpwood, while most older ones are good enough for saw timber. The final wood quality can be improved by pruning small branches at ages 5, 7, and 9.

This results in smooth timber with no knots, which is considerably more valuable. A year-old commercial pine tree grown in good conditions will be about 0. After 50 years, the same tree will be about 0.

Some species have large seeds , called pine nuts , that are harvested and sold for cooking and baking. They are an essential ingredient of pesto alla genovese.

The soft, moist, white inner bark cambium found clinging to the woody outer bark is edible and very high in vitamins A and C. It can be eaten raw in slices as a snack or dried and ground up into a powder for use as an ersatz flour or thickener in stews, soups, and other foods, such as bark bread. A tea made by steeping young, green pine needles in boiling water known as tallstrunt in Sweden is high in vitamins A and C. In eastern Asia, pine and other conifers are accepted among consumers as a beverage product, and used in teas, as well as wine.
