The difference between Scots and Scotch pine lies primarily in their names and their geographical origins. Scots pine, also known as Pinus sylvestris, is native to Europe, particularly Scotland, hence its common name. On the other hand, Scotch pine, also known as Pinus sylvestris var. Scotch Pine, is a variety of Scots pine that is commonly found in North America.
In terms of their physical characteristics, Scots pine and Scotch pine are quite similar. They are both fast-growing conifers that have a conical to columnar shape. They can reach medium-sized heights, typically around 50 to 80 feet tall, with a spread of about 20 to 40 feet. Both species have distinctive flaking bark that ranges in color from orange to red-brown, adding visual interest to their overall appearance.
While Scots pine is native to Europe, it has been widely planted and naturalized in many parts of North America, including the Midwest. It has historically been a popular choice for landscaping due to its fast growth and attractive appearance. However, in recent years, Scots pine has been facing a significant threat from a disease called Pine Wilt.
Pine Wilt, caused by the nematode Bursaphelenchus xylophilus, is a devastating disease that affects various pine species, including Scots pine. It is spread by pine sawyer beetles and can rapidly kill infected trees. Unfortunately, there is no effective treatment for Pine Wilt, and infected trees often need to be removed to prevent the spread of the disease to other nearby pines.
Due to the prevalence of Pine Wilt and its destructive impact on Scots pine, it is no longer recommended for planting in Nebraska and other areas where the disease is present. Instead, it is advisable to choose alternative pine species that are more resistant to Pine Wilt.
While Scots pine and Scotch pine are often used interchangeably, the latter refers specifically to the variety of Scots pine found in North America. Both species share similar physical characteristics but are now facing challenges due to the widespread occurrence of Pine Wilt. As a result, it is recommended to avoid planting Scots pine, including the Scotch pine variety, in areas where Pine Wilt is prevalent.
