With around 115 unique species, there are a number of different types of pine trees, ranging from scraggly pinyon to the statuesque bull pine. Pines have a number of different uses, including as food, fuel, and construction material, and many species are especially well-suited to certain applications. Many garden stores carry pine trees suitable for landscaping, and chances are high that a local hardware store has some examples of pine lumber on display.
Many pine trees take well to a variety of soil and climate conditions, making it easy for people to establish new plantations of pines for varying purposes. These hardy, rugged trees are especially popular with people who landscape roads and medians, since they will thrive when other plant species might give not, and different types of pine trees can be planted in contrasting patterns to create an interesting visual effect.
Pines are conifers native to the Northern hemisphere. In addition to producing the trademark cones associated with this type of tree, they also have distinctive needles, instead of leaves, although the needles of each species can have radically different appearances, from short and twisty to long and straight. Pines have adapted to a wide range of environments in Europe, Asia, and North America, including extremely cold regions, arid areas, heavily salted environments like the seashore, and neighborhoods prone to forest fires.
The largest pines are the bull pine, also known as the western yellow pine, and the sugar pine. The sugar pine also produces the largest cones of any species, and both of these trees are found along the West Coast of the United States. They are sometimes used for erosion control, since they establish extensive root systems, although if they become diseased, they can fall easily.
Pitch pines produce a lot of sap, and they are extremely hardy. They also rely on fire to germinate their seeds, with seedlings appearing rapidly in the wake of a forest fire. The loblolly pine has adapted to swampy areas, producing straggled limbs which often become twisted and deformed from the wind, while the Cuban pine has lacy spreading foliage.
In landscaping, some people like to use bristlecone pines, along with lacebark and ponderosa pines. The black or Austrian pine if often grown for fuel, while white pines are prized for their white wood. Jack pines are scraggled like their pitch pine relatives, but they also grow in salty areas, producing twisted limbs that bend with the wind and climate conditions.
People who want to learn to recognize the different types of pine trees can find conifer identification keys, which guide users through a flowchart of options that can be used to positively identify various species.
