Austrian pine (Pinus nigra) is a coniferous evergreen tree native to Austria, Italy, and the Balkans. It is widely planted as an ornamental tree in many parts of the world due to its attractive appearance and hardiness.

A mature Austrian pine tree can reach a height of 40 to 60 feet (12 to 18 meters) and a spread of 20 to 40 feet (6 to 12 meters). It has a dense, pyramidal to rounded crown with a straight trunk and a rough, dark gray bark. The needles of the Austrian pine are dark green, stiff, and about 3 to 6 inches (7.6 to 15 cm) long. The tree also produces brown cones that are about 2 to 4 inches (5 to 10 cm) long.

Austrian pine is a hardy tree that can tolerate a wide range of soil conditions and is resistant to drought and air pollution. It is commonly used in windbreaks, screens, and as a specimen tree in landscapes. However, it is important to note that Austrian pine can be susceptible to some pests and diseases, such as pine wilt and tip blight, so proper care and management is necessary to keep the tree healthy.
