Pinus nigra (Austrian Pine) Seeds

Zones: 4 to 8.

Native to Europe and Anatolia and naturalized in many parts of North America.

The Austrian pine is an adaptable tree that was widely planted in the American Great Plains states in the 1930’s during the Great Plains Shelterbelt to prevent erosion during the great drought of that period. It is widely planted as an ornamental tree in gardens and parks and can be long lived. When young it has a densely-branched conical form that becomes more broad and irregular with age. It features dark green needles grown in bundles of two, 4 to 6 inches (10 to 15 cm) long that persist for 4 to 8 years. Cones are oval, light brown and woody when mature, borne in clusters of 1 to 4.  The bark is brown to grey with furrows. This large evergreen provides food and shelter and nesting sites for birds.

The Austrian pine prefers full sun and does well on a variety of soils, but prefers average to moist sandy loam and has some drought tolerance once established.

Size: Height 50 to 60 ft; Width 20 to 40 ft.
