Bog Birch

Scientific name

Betula pumila


Bog Birch is a medium sized deciduous shrub species that typically grows 1-3 m in height. This plant may also be known by the common name Swamp Birch. The leaves are alternately arranged, dark green coloured, simple, broadly rounded or fan shaped, have coarsely rounded or dentate toothed margins, and are 1-3 cm long. The lower trunk is grey while the stems are brownish red coloured and have scattered white lenticels. This shrub produces stout, upright catkins in April to May, which are cylinder shaped clusters of flowers. Bog Birch has both male and female catkins on the same plant. In the fall, tiny, greenish brown samara seeds with wings are developed and dispersed by wind. The Bog Birch is a good food source for wildlife including many bird species, mammals, and insects.
