White oak is a large tree, growing up to 100 feet tall. It’s leaves are four to nine inches long and lobed. They are bright green on top, and a light color underneath. White oaks have male and female flowers. The male flowers are greenish-yellow catkins about four inches long while female flowers are small reddish spikes. White oaks will produce an acorn fruit with a saucer top. The bark is usually light grey-brown scaly and sometimes peels off.
