About Betula pumila L.
Betula pumila L. is a birch species that grows to a height of 1–4 meters (3–13 feet). Like other birches, Betula pumila L. is monoecious, and produces catkins as its reproductive structures. Its leaves are arranged alternately along stems, but grow close together, particularly on slow-growing individuals. The leaves have coarse teeth along their edges and are rounded at the base.
