Quercus garryana
Also called Brewer Oak, Garry Oak, Post Oak, Oregon Oak
Oregon white oak is a slow-growing deciduous oak of the Pacific Northwest, usually a medium tree to about 24 m or a shrub form, valued for its wildlife and acorns. It needs full sun and well-drained soil, and it tends to do best where summers are dry.
Quercus garryana is an oak tree species found most commonly in the Pacific Northwest, with a range stretching from southern California to southwestern British Columbia. It is commonly known as the Garry oak, Oregon white oak or Oregon oak. It is named for Nicholas Garry, deputy governor of the Hudson's Bay Company.
It grows from sea level to an elevation of 690 ft (210 m) in the northern part of its range, and from 980 to 5,900 ft (300 to 1,800 m) in the south of the range in California.
The mildly sweet (but perhaps unpalatable) acorns are edible, ideally after leaching. The bitterness of the toxic tannic acid would likely prevent anyone from eating enough to become ill. Native Americans ate the acorns raw and roasted, also using them to make a kind of flour.
