River Birch


The River Birch tree is known for its distinctive salmon-colored bark, which peels back year-round in paper-like layers to reveal a lighter-colored wood underneath. It most commonly occurs in floodplains and swamps. It grows rapidly and can reach between 40 and 90 feet in height at maturity. Its leaves turn a brilliant yellow color in Autumn as well.
