13 Most Common North American Pine Species

Pine trees are grown for beautifying the landscape, creating privacy screens, and also, for collecting timber. This Gardenerdy article deals with how fast pine trees grow, and provides some helpful information on quick-growing pine varieties that are used for landscaping projects. The slow-growing bristlecone pine Pinus aristata are the oldest living trees, with one of them present in the Great Basin National Park, in Nevada, which is about 4, years old. They grow in USDA hardiness zones 4 through 8. Trees are generally slow growers, and take a few decades to attain their maximum size. However, some cultivars develop at an exceptionally slow rate. For those of you who have recently shifted to a new place and plan to starting landscaping right from scratch, planting fast-growing trees is a practical solution. One such tree that grows fast and makes an attractive specimen in the landscape is none other than the pine. They are the most common coniferous trees grown all over the world, having about species. They look amazingly attractive during winters, and are mostly used as Christmas trees, especially the Scotch pine trees, during the festive season. Let us find out the growth rate of some species of pine trees. Different types of pines are used for different purposes in landscaping. This feature makes them perfect for creating privacy screens, protecting properties, and windbreak barriers against winds. They also look adorable with their needle-shaped foliage. But one thing that concerns landscapers is the rate at which they grow. Well, the answer differs from species to species and the growth conditions that are provided to them. On an average, the yearly growth rate of pine trees is less than a foot to more than two feet. Thus, according to the growth rate per year, they are broadly grouped into three types, viz. Examples of slow-growing pine trees are Virginia pine and longleaf pine. They grow to a maximum of one foot a year. The medium-fast growing pine trees grow about feet per year, and examples are red pine and Austrian pines. Lastly, the fast-growing pines grow up to two feet and more annually. Talk about pine trees that grow rapidly, and the Australian pine is commonly included in the list.

How to Determine the Age of a Tree

Learn which plants thrive in your Hardiness Zone with our new interactive map! The ponderosa pine tree Pinus ponderosa is a large evergreen that lives to years. Native to mountain and plateau regions of the United States, the ponderosa pine develops a taproot early in life that enables the tree to survive stressful conditions such as extended drought. The tree is naturally a slow grower. The ponderosa pine typically reaches to feet in height with a trunk that is 3 to 4 feet in diameter. Especially old specimens have been measured at more than feet tall with trunks 7 feet in diameter. The ponderosa pine has a straight trunk, the lower half of which is branchless. The tree's crown has a rounded cone shape, and the scaly bark is orange-brown. The ponderosa pine's pointy, serrated needles are 5 to 10 inches long and usually appear in groups of 3. Flowering occurs from April to June, and pineapple-shaped, prickly male and female cones develop on the tree. The cones mature and produce seeds in August and September of the following year. The bark on young ponderosa pines is black and scaly. As the trees mature, the bark thickens to as much as 4 inches and develops into large, flat plates separated by deep fissures. Old trees have yellow bark, which is why the tree is commonly called yellow pine. The bark of mature trees smells like vanilla or butterscotch, and the wood of old ponderosa trees is prized for its strength, light weight and fine grain. The wood is commonly used for lumber, railroad ties and millwork. Ponderosa pines grow in USDA hardiness zones 3 through 7. Common in mountain and plateau areas at elevations of 5, to 8, feet, it grows in mixed conifer forests, as well as in groves on its own. Ponderosa pines grow in a wide variety of soil types, from sandy to clay, and it's even found thriving on rocks with roots growing in cracks and crevices. The tree does best in well-draining soil that has a pH of 6. Established ponderosa pines survive in hot, dry locations with little irrigation, although they grow best when the average annual rainfall is 12 to 24 inches. The tree also survives freezing temperatures. Ponderosa pines grow from seeds that come from the cones. Once planted, the seeds germinate in about 15 days when the temperature is around 68 degrees Fahrenheit. Share this article. Habeck; Leatherman, et al.

How Fast Do Pine Trees Grow?

There are about species of pines worldwide, although different authorities accept between and species. Pines are evergreen and resinous trees rarely shrubs. Pines are among the most plentiful and commercially important of tree species, valued for their timber and wood pulp throughout the world. In temperate and semi-tropical regions, pines are fast-growing softwoods that will grow in relatively dense stands, their acidic decaying needles inhibiting the sprouting of competing hardwoods. They are often grown in plantation managed forests for both lumber and paper. There are actually 49 species of native pines in North America. Pines are especially widespread and predominant in the Southeast and on drier sites in the Western mountains. Here are the most common and valuable pines that are native to the United States and Canada. Leaves: All of these common pines have needles in bundles of between 2 and 5 needles and wrapped sheathed together with paper-thin scales that attach to the twig. The needles in these bundles become the tree's "leaf" that persists for two years before dropping as the tree continues to grow new needles every year. Even as the needles are dropping bi-annually, the pine maintains its evergreen appearance. Cones: Pines have two types of cones - one to produce pollen and one to develop and drop seeds. Pine cones usually mature in the second year, dropping a winged seed from between each cone scale. Depending on the species of pine, empty cones may drop off immediately after seed fall or hang on for several years or many years. Some pines have "fire cones" that only open after the heat from a wildland or prescribed fire releases the seed. Bark and Limbs: A pine species with smooth bark generally grows in an environment where a fire is limited. Pine species that have adapted to a fire ecosystem will have scaly and furrowed bark. A conifer, when seen with tufted needles on stout limbs is confirmation that the tree is in the genus Pinus. Gernandt, David. Gernandt, Jorge A. Share Flipboard Email. Steve Nix. Forestry Expert.

Pine Tree Facts for Kids

Learn which plants thrive in your Hardiness Zone with our new interactive map! Pine trees in the winter make a picturesque landscape; nothing is more beautiful than pine trees in the winter covered in snow. Pine trees are best known for their pine cones and lovely evergreen needles. These trees are harvested around the world and sold as Christmas trees every year. They are also used as a material in furniture making. There are over species of pine trees in the world. The United States has around 35 different types of pine trees growing nationwide. Some of the most common pine trees are spruces, noble fir, sequoias and bristlecone pine. The Scots pine and Austrian pine have been introduced into the United States for ornamental purposes. The largest tree in the world happens to be a pine tree. The tree is a sequoia or also known as a redwood tree and is named Hyperion. The sequoia was measured at That means the trees roots started growing around the time of the last ice age. The spruce is only 13 feet tall, but these trees are known to live only years; however, when the tree dies the roots introduce a new seedling in the place of the old tree, rejuvenating itself. Pine trees are most notably sought out as Christmas trees. Popular pine species chosen for Christmas tree cultivation are noble fir, douglas fir, fraser fir, Virginia pine, spruces and Scotch pine. The leading Christmas tree producing state is Oregon, with over 8. The pine tree species is the only type of trees that reproduce from the seeds that are enclosed inside of pine cones. Pine cones are actually the flowers of pine trees. The heaviest pine cones in the world are from a coulter pine; they can weigh up to 10 lbs. The longest pine cones are those of the sugar pine tree; these cones can grow up to 24 inches or more. Pine cones are used for food for animals, decorations and crafts. Share this article.

Tree structure and growth

As a pine tree grows, the trunk and branches get thicker. Each year adds another layer of wood. Other methods such as calculating the diameter of the tree or counting the whorls of a pine tree are useful tools for estimating age. Measure the circumference of the tree trunk at about 54 inches above the ground or chest height. Using the formula of diameter equals the circumference divided by pi, calculate the diameter of the tree. A pine tree with a chest-high circumference of 70 inches has a diameter of about The International Society of Arboriculture, the organization responsible for creating this formula, assigned a growth factor number to various species of trees according to their average growth rate. The white pine tree has a growth factor of 5. A white pine tree with a chest-high circumference of 70 inches is about years old. Also, this formula is more accurate with forest-grown trees than with trees grown in the urban landscape because the growth factor is based on the growth rate of trees in the wild. Irrigation and applications of fertilizers by homeowners and park maintenance workers prevent maintained trees from experiencing true growth based strictly on natural condition. The age of a pine tree can also be determined by counting whorls. As a pine tree grows each year, new branches form a circle, or whorl, around the trunk. The number of whorls is an approximation of the age of the tree. However, being able to see and count the whorls on very old trees may be difficult and impractical.
