Oregon White Oak
Quercus garryana
The Northwest's iconic prairie-savanna oak, a slow, gnarled tree supporting an extraordinary web of wildlife. The keystone of the region's vanishing oak woodlands. Its acorns are traditional food, sweet enough on some trees to need little leaching before grinding into flour.
