Pinus subg. Stobus: These includes trees from the white or soft pine groups.
Pinus subg. Ducampopinus: These are pines from the pinyon or foxtail group.
Pinus subg. Pinus: These are trees from the yellow or hard pine group.
Pine Tree Types
There are about 35 pine tree species in America. They are classified as evergreen plants, as they do not shed their leaves even in winter. They are very hard, slow-growing trees that are resistant to drought and can survive in poor, sandy soil. The Norway pine and Ponderosa pine are pine tree types that can grow up to a height of 70 to 80 feet. The Western White Pine tree species can reach a height of 110 feet.
One of the slow-growing pine tree species is the Bristlecone pine that can reach a height of 25 feet. The Mexican pine is known for its long, beautiful foliage and looks similar to the Weeping Willow. Therefore, this gives rise to an interesting pine tree fact that it is also known as Willow pine. Other common varieties include sugar pines, pirions, white pines, long leaf pines, red pines, foxtail pines, shortleaf pines, stone pines, bristlecone pines, Ponderosa pine, and Monterey pine
Pine Tree Identification
Pine tree identification is very easy, as these trees stand out among a group of trees. These are coniferous trees and have leaves that look like needles, are in fascicles or bundles. They have a deciduous sheath and the stems branch out in whorls of ‘racemose arrangement’. The leaves are dark green in color and are variously arranged. The peculiarity of genus Pinus is they have different kinds of leaves. The first types are small membranous scales and second prismatic green needles in groups of 2, 3 or 5 dwarf branches in the axils of their scales.
Pine trees have different and distinct inflorescence of stamens and ovules. The cones are ½ to 12 inches in size. The Longleaf pine tree species are up to 10 inches in size that makes it one of the largest pine cones. Another pine tree fact is that the smallest cone is just 3/4″ to 2″ in size and it belongs to the Mugo pine tree species. They are known to cross-pollinate naturally and produce naturally evolved and improved pine tree species.
Pine Tree Diseases
Pine tree diseases, if not diagnosed early can lead to many ill consequences. If the diseases are not treated early on, you may have to remove the tree from your lawn permanently.
