Pine trees have long, needle-like leaves, and produce cones for reproduction. The branches grow out of the trunk in a whirl-like pattern. Pine seeds from the cones feed local wildlife, such as squirrels and birds. Some pines reach several hundred feet in height, and can survive for over 4,000 years. Others may live less than 50 years. Pine trees grow rapidly, and mature specimens range in height from 15 to several hundred feet tall.
Homeowners commonly plant pines for windbreaks or privacy screens. Pine trees are used for timber and wood pulp production. Pines are popular as Christmas trees, and the cones and boughs are also used in Christmas decorations. Furniture, railroad ties and ship masts are all produced from pines. Nuts from the pine can be used in cooking and baking.
Pine trees produce both male and female cones. Both kinds of cone are produced on the same plant, but they look quite different from each other: the female cone appears woodier. Pollen from the male cone pollinates the female cone, which then produces seeds. The seeds are "winged," so that they can be carried by the wind when they are released from the cone. Although pine seeds may float some distance, most new trees grow within 90 feet from the original tree.
Some of the more popular pines found in the United States include the white pines. White pines are a popular tree for woodworking, and also a popular landscape tree. Giant pines include the sugar pine, longleaf pine, and yellow pine. These are commonly used for masts on large ships. The bristlecone pine is a shorter tree that is popular in rock gardens. Ponderosa pine trees are some of the most popular trees, and are used in landscaping all over the United States, in many more locations than all other pine trees.
Pine trees are highly drought-tolerant and can thrive in a number of soil types, although they prefer acidic, well-drained soil. They also prefer full sun. Pines are easily destroyed by fire, because of their shallow root system and thin bark. But some species, such as the bristlecone pine, are native to climates with short growing seasons and much colder temperatures, and are therefore not in much danger from fires. Pines grow at elevations from sea level to just under 13,000 feet.
