River Birch (Betula nigra) is one of the few heat-tolerant birches of the birch tree family. This deciduous tree can grow to be 80-100 ft. tall with multiple, slender trunks coming off of the base. It is predominately found along streams or forested wetland communities. Bark is loose and layered, often described as scales. Often used for landscaping, the River Birch is also beneficial to many bird species and can be used for essential oils.
