Quercus garryana var. garryana

Oregon oak

Family: Fagaceae · Type: tree · Native

Oregon oak is a California native tree found in northwestern California, central California Ranges, San Francisco Bay Area, and southern coastal ranges in mixed-evergreen and conifer forest slopes at elevations of 90 to 2,140 meters. Flowering from April to June, this oak produces pale green to yellowish flowers in small, clustered catkins. Growing to heights of 10 to 25 meters with a broad, spreading canopy, it develops dense, yellowish to white-haired terminal buds that are fusiform in shape. Its leaves are broadly lobed, 7 to 14 centimeters long, with irregular rounded edges that provide a distinctive textured appearance. The tree forms acorns characteristic of its genus, providing important wildlife habitat in its native woodland ecosystems.
