River BirchBetula nigra
As its name suggests, the river birch naturally grows along riverbanks. But as a landscape tree, it can be planted almost anywhere in the U.S. The species is valued for its relatively rapid growth, tolerance of wetness and some drought, unique curling bark, spreading limbs, and relative resistance to birch borer.
The river birch has not yet reached the popularity of many maples and oaks, but it is well on its way. In 2002, one of its cultivars was even named the Urban Tree of the Year by the Society of Municipal Arborists.
