Last updated
Pinus nigra (Pinaceae) is a large two-needled pine native to the Mediterranean region and the Balkans. It grows to 120 feet tall with a dense, broadly pyramidal crown and dark, deeply furrowed bark. The stiff, dark green needles (3 to 6 inches) are held in pairs.
Austrian pine is widely planted as a landscape and windbreak tree due to its tolerance of urban conditions, salt, drought, and a range of soil types including clay and alkaline substrates. It grows in full sun. The species is susceptible to Diplodia tip blight and Dothistroma needle blight, which have caused significant decline in some regions. Hardy in Zones 4a to 8b.
