Live oak was widely used in early American butt shipbuilding.Because of the trees' short height and low-hanging branches, lumber from live oaks was used in curved parts of the frame, such as knee braces (single-piece, L-shaped braces that spring inward from the side and support the deck), in which the grain runs perpendicular to structural stress, making for exceptional strength.
Although live oaks retain their leaves nearly year-round, they are not true evergreens.Live oaks drop their leaves immediately before new leaves emerge in the spring. Occasionally, senescing leaves may turn yellow or contain brown spots in the winter, leading to the mistaken belief that the tree has oak wilt, whose symptoms typically occur in the sum

A small- to medium-sized tree, the sand live oak is scrubby and forms thickets. The bark is dark, thick, furrowed, and roughly ridged. The leaves are thick, leathery, and coarsely veined, with extremely revolute margins, giving them the appearance of inverted shallow bowls; their tops dark green, their bottoms dull gray and very tightly tomentose, and their petioles densely pubescent, they are ...

The interior live oak is a red oak (section Lobatae) in the California Floristic Province (series Agrifoliae). Q. wislizeni hybridizes with California black oak (Q. kelloggii) (= Quercus × morehus, Abram's oak). All California red oaks show evidence of introgression and/or hybridization with one another.
