Black birch is a tree (this is the common birch tree) that grows 60-80 feet high; the bark is brown when the tree is young, dark gray later, and is horizontally striped. Bark is non-peeling, sweet, aromatic. On old trees the bark is more irregularly broken. The ovate, pointed leaves, 6 inches long, occur alternately in pairs and are finely serrate. The flowers grow in inconspicuous male catkins about 3 inches long and female catkins about 1 inch long, the male appearing in the fall and the female the following spring. The fruits are oblong, upright, 3/4 inch long. The bark and small twigs have a flavor similar to wintergreen.
