The White Birch has simple alternately arranged leaves that are 2–4 inches long on leaf stems about 1 inch in length. They are medium green in color and have double serrate margins. Defined by a smooth white bark that curls and peels when the tree begins to mature. Typically has a height from 50-70 feet once mature. Produces brown or green catkins in April/May and the leaves turn a bright yellow during autumn.
