This impressive tree also grows impressive cones and has the name the “big-cone pine tree.” In fact, the coulter pine produces the heaviest cones of any pine tree.

Bruce Watt/University of Maine/Bugwood.org. Pitch pines are small to medium-sized trees that reach modest heights of between 20 and 98 ft. (6 – 30 m). Most species have fascicles of 2 to 5 needles; only occasional species typically have as few as one or as many as six leaves to the fascicle. You can also tell the species apart with the dark bark in rectangular shapes on the shortleaf species. Red pine needles are long and brittle and snap easily. Pine needles grow in clusters on the twigs while fir needles are softer and are attached singularly to the branch. The long woody dark brown cones can grow up to 20” (50 cm) long. The Virginia pine is a medium-sized species of pine tree with short pine needles and large seed cones. Monterey pine trees are a medium-dense type of softwood conifer. Leaf fascicles are present in all pines, and the number of adult leaves (needles) per fascicle is an important character for identification of pine species and genera. Due to its extremely long and straight trunk, this pine species is prized in the timber industry. Knowing the difference between a "broadleaved" bladed leaf of a hardwood and a "needle-like" leaf of a conifer is important and is fundamental in the process of tree identification.

This makes the species an important tree in the timber industry. Some species of the family Alseuosmiaceae have flowers in fascicles. The red pine is an evergreen conifer that is characterized by a tall straight trunk, conical shape, and egg-shaped cones.

These two characters readily distinguish the major groups of pines (see Pinus classification).

The soft gray pine needles give the tree a drooping look and there are 3 needles per cluster. Longleaf pines grow to between 100 and 115 ft. (30 – 35 m) with the tallest being 154 ft. (47 m). Different types of pine trees grow in many different environments that include cold regions in North America, rain forests, and hot sandy deserts. Scots (Scotch) pines have bluish-green short needles. These are also a resinous pine that is prized for its high-quality softwood timber. Most larches have multiple clusters of needles in whorls. Pinus durangensis (Durango pine) has fascicles of 6 needles, rarely 7, and is the only species in Pinus with so many needles per fascicle. Another identifying feature of pine trees is their egg-shaped cones that hang down from branches. Needles are a dull dark green color and are 6” to 12” (15 – 30 cm) in length. The number of adult needles per fascicle is important for the identification of these coniferous species, especially the pines. As well as their scientific name, descriptions of pines and pictures of pine trees will help you identify them.

The cones can be dark purple to red-brown, depending on the exact subspecies.

The shortleaf pine is a type of yellow pine tree similar to the longleaf pine, only with shorter needle leaves. Their yellowish-green needles are twisted and only about 1.5” (4 cm) long. Variation is high between species, low within them.

The needles on Virginia pines are not soft and are quite sharp to touch. In optimum conditions, Monterey pines can grow to 200 ft. (60 m). Other plant fascicles are adaptations to achieve greater compactness for defensive reasons. (2 – 5 kg)! Sugar pines also have the longest cones of any tree in the Pinaceae family. These massive pine trees also have large spiny tan-colored cones, long gray-green pine needles, and reddish-brown bark. The long needle-like leaves grow to between 8” and 18” (20 – 45 cm). Slash pines grow to between 60 and 100 ft. (18 – 30 m). Jack pines can range in size from 30 to 72 ft. (9 – 22 m). One of the identifying features of Jack pines is their small yellowish prickly cones that are curved at their tip. Whitebark pine trees are classified in the group of white pines.

Their needle-like leaves are just 0.78” to 3.14” (2 – 8 cm) in length and they grow in 2 needles per cluster. Cones from the longleaf species measure about 6” to 10” (15 – 25 cm) long and are reddish-brown. Whitebark pines are usually pines that grow at the highest elevations on mountains.

Pinyon Pine has short needles that grow in pairs, Also called the Colorado pinyon, this medium-sized bushy pine tree grows in hot or cold unforgiving climates. As its common name suggests, the bark on this pine is a whitish color rather than the typical red or charcoal-gray. [1] However, vascular tissues may occur in fascicles even when the organs they supply are not fascicled. On mature trees, the bark is rough and gray in color.

Needles grow to about 5” (12 cm) and they have tiny cones compared to the longleaf pines. These pines can also create pine hybrids with other species that are common in the southern states of the U.S. such as the longleaf pine and loblolly pine. Similar to the longleaf variety, these southern pines are an important species in the timber industry. Each bundle is called fascicle. The taller varieties are some of the largest pine species that grow in the U.S. Lodgepole pines generally grow at high altitudes in coastal or cold mountainous areas. They are common in high altitudes in the cold Rocky Mountains and also grow in the hot Arizona desert. The green flexible needles grow to around 8” (20 cm) and they have 3 in each bundle growing on the shoots. Its long pine needles are light green in color and have white lines running their length. It can be difficult to distinguish between the subspecies. The trees are identified by their short needles that grow in bundles of 2, but sometimes 3 or 4. The red pine gets its name from the red-orange bark that grows on the upper part of the tree. Coulter pines have long needles and large heavy cones. Most species have fascicles of 2 to 5 needles; only occasional species typically have as few as one or as many as six leaves to the fascicle. The pine tree is characterized by upward-pointing branches that have clusters of needles to create dense foliage. Jack pines, similar to pitch pines, have an irregular shape, dark green needle foliage, and grow in poor soil conditions. Longleaf pine (pinus palustris) has the longest pine needles measuring 18” (45 cm) long. These cones open in heat or if there is a fire. Even though this is a huge type of tree, you can prune it to create a landscaping pine tree bush. Virginia pine has short needles that are quite sharp. Most pine species have fascicles of from 2 to 5 needles and are evergreen.
