About plant names...

Austrian pines were introduced to the United States 1759. This cultivar was developed for landscaping use as a tall, narrow, columnar tree.

Identification: Trees are 20' (6.1 m) tall, and oval and narrow in shape. Needles are in clusters of two, 4" (10 cm) long, stiffer and denser than those of red pines. Inconspicuous flowers occur for a short time in April or May. Male flowers are clusters of orange-yellow catkins, while female flowers are small yellow-green conelike structures. Cones are up to 3" (7.6 cm) long, and pale brown or yellow brown in color.
