Oregon White Oak
Quercus garryana
About this plant
Quercus garryana
Type: Tree · Family: Fagaceae · Native Region: Pacific Northwest
There's no other way to say it, Oregon White Oak (AKA Garry Oak) is the Willamette Valley's most ecologically + culturally significant keystone plant relative. Since time immemorial, indigenous people have co-managed the Willamette Valley's landscape together with White Oaks to create Oak Savannahs, a unique ecology paramount to the region's biological health. White Oaks provide food and habitat for more than 200 species of insects, birds, and mammals, and are incredibly long lived, drought tolerant, and fire resistant. Kênawi (acorns in Chinook Wawa) are an important perennial source of protein, vitamins, and fat to many oak tending native cultures. Pre-colonization, White Oak Savannahs dominated the Valley floor, but now less than 2% remain, and in Portland less than 1%. Planting a White Oak is a true gift to future generations, especially when sited somewhere their iconic wandering canopies can spread out for all to enjoy.
