Birch trees typically exhibit an alternate leaf arrangement, meaning that the leaves are positioned alternately along the stem rather than directly across from each other. The leaves are usually simple and can be ovate to triangular in shape, with serrated edges. They are often glossy green in the summer, turning vibrant yellow in the fall. This arrangement allows for optimal light exposure and air circulation among the leaves.
