| Identification | When mature, Gray Birch has bark that is grayish white or dull white, with much black where branches attach. Leaves are triangular, margins serrate, the tip elongate-tapered. It is very similar to Silver Birch (B. pendula), a Eurasian species, which has whiter bark and leaves that are far less acuminate at the tip. | |
