Betula pumila (Swamp or Bog Birch) is a deciduous shrub native to North America. It reaches 1-4 meters in height. Its reproductive structures are monoecious catkin similar to other birches. Bog Birch occurs over a vast area of northern North America, from Yukon in the west to New England in the east and all the way to Washington and Oregon, inhabiting swamps and riparian zones in the boreal forests.

Its twigs develop on spur shoots. Leaves are alternate but close together, especially on slow growing individuals. Leaves are coarsely dentate and rounded at the base.
