California white oak

The California white oak, also known as Quercus lobata, roble, or valley oak, is a tall, graceful tree native to California. It is often planted as a shade tree. This oak species is characterized by its deep-lobed leaves, which are dark green on top and whitish underneath, and its long, conical acorns that are nearly sessile.1

The California white oak belongs to the white oak group, which are trees and shrubs in the genus Quercus known for their smooth, bristleless leaves and sweet-tasting acorns that mature in one season. While the name "white oak" can refer to a group of species, it specifically denotes Quercus alba, an important timber tree in the eastern United States. The California white oak, however, is primarily valued for its ornamental and shade tree qualities.2
