Scientific Name
Pinus heldreichii ‘Bosnian Pine’
Bosnian pine has an interesting and scattered distribution across the mountainous regions of the Balkans and Greece, with a smaller isolated population in southern Italy. It grows up to the alpine tree line at around 8,000 feet. Despite its limited and fragmented native range, the species is not currently considered a conservation concern.
This is an exceptionally tough and long-lived pine, with some verified specimens exceeding 1,000 years of age. It tolerates temperatures below minus 40 degrees Fahrenheit and is resistant to wind, ice, snow loading and various forms of pollution, including salt. It is also less susceptible to insect pests than many other pine species.
Bosnian pine has dark green needles 2 to 4 inches long that grow in bundles of two. The tree grows somewhat slowly, forming a compact and symmetrical pyramidal shape with dense foliage. Young seed cones are around 3 inches long and display a handsome bluish-purple color before maturing to light brown. In cultivation, Bosnian pine may reach about 40 feet tall.
Over the past few decades, the species has been planted increasingly throughout this region because of its tolerance for summer heat, salt, poor soil and drought. However, many of these trees may not yet have reached their mature size, as the current Colorado champion specimens measure between 25 and 32 feet tall.
