What does a Bosnian pine tree look like?

The Bosnian pine is a slow-growing tree that reaches heights of 50 to 70 feet when it’s fully mature. The spread of its branches can span 10 to 15 feet in width, making the shape of a Bosnian pine tree tall and narrow. Their pine needles are dark green and grow to a medium length, and the bark is light grey. Bosnian pines also produce cones that are around three inches long.  They tend to hold their needles much longer than many of our other pines planted for our area.

Although there are nearly 100 different types of pine trees in the northern hemisphere alone, the Bosnian pine sets itself apart by growing tall and narrow, and it’s branches aren’t as dense as other species, making it easier to see between them. This makes it a perfect tree for planting in your yard, since it doesn’t overpower other trees and plants.
