NW of the Fine Arts Building Map

With long needles in bundles of two, this small tree (in 2012) tree can grow to over 100 feet with a 6-foot trunk diameter. WWU graduates returning for their 50th class reunions will be able to enjoy the shade from this little guy.

As its name implies, the Bosnian pine is native to the Balkans, and can live for more than 1000 years. One speciman in the mountains of Bulgaria is estimated to be over 1300 years old. The largest in Washington is 52 ft. tall, located in the U.W. Arboretum. The species was introduced to North America in the early 1900s and is now fairly widespread.

It's long needles held close to the twig give the shoots the appearance of a bottle-brush. It is also noted for its very decorative purple cones.
