The silver birch is a medium-sized tree, which has triangle-shaped leaves. In autumn the leaves turn yellow and fall. Trunk is shining white. The twigs are slender, and in an old tree the they often hang downwards. The flowers are grouped in an inflorescence called a catkin. The wind spreads the birch seed. The trees are monoecious, with both male and female catkins on the same tree.
