Looking for a fast-growing, hardy tree that can thrive in wet spots? Look no further than Betula nigra, also known as River Birch or Water Birch. This deciduous tree is native to the eastern United States, from New Hampshire to Texas, and can reach heights of up to 80 feet. Its bark peels off in unique sheets, revealing reddish-brown underbark, and its shiny green leaves turn yellow in the fall. Betula nigra prefers rich, moist, and acidic soil and is a great choice for flood plains or swamps. It can grow up to 2 feet a year, making it an excellent choice for those looking for a quick-growing plant. Hardy to zone 4, this tree is also wind-pollinated and produces abundant tiny winged seeds in late spring. Its rapid growth rate and ability to thrive in wet conditions make it a great addition to any landscape design.
