The Valley Oak is the tallest oak in North America. Native to California’s valleys and foothills especially near rivers, it forms a large tree with spreading branches that may hang down to the ground. The leaves are deeply lobed and stay green in summer, unlike the Blue Oak. Large acorns are produced when the tree becomes mature.
This California native oak does best with very infrequent summer irrigation.
