Oregon White Oak

Oregon White Oak

The iconic oak of the Willamette Valley, the Oregon White Oak was a key part of the oak savannah that dominated the Willamette Valley prior to European invasion. Trees can eventually reach a stately 100 feet or so and their gorgeous spreading form is quite the sight to behold on older specimens. Some trees of great age can still be seen in pockets of the valley. Excellent wildlife tree and a true gift to future generations, wherever they may be planted.
