Identification of Pines
There are more than 100 known varieties of these evergreen, resinous pines. The most important of these fall under the evergreen, conifer, and softwood categories. Following is a list of the major ones found in the northern hemisphere.
It can be easily identified by its height of almost 175-200 feet. Some old ones have been around for nearly 500 years. Its soft, even-grained and finely textured timber is matchless in quality and value. It has long, pendulous cones hanging on the tips of asymmetrical branches.
It is found in the western slopes of the Cascade Range in north central Oregon, and all the way to the Sierra San Pedro Martir in Baja, California.
The pinus palustris has the longest needles found on any native pine tree. These needle-like leaves grow nearly 18 inches in length, and in bundles of three. The longleaf seedlings form masses of long, green needles, and stay in a protective state for several years, protecting the tree from the grasses around it, that are prone to fire during dry periods.
Besides the mentioned, there are other varieties such as ponderosa pine, slash pine, pitch pine, etc. They are all harvested for commercial and ornamental purposes. In the wild, nature takes care of pine trees. However, for those who use them in their landscaping designs, care and maintenance is required until they reach maturity.
