River Birch trees grow quickly to a maximum height of 40 to 60 feet tall. The Betula Nigra River Birch has a stunning yellow-golden color in the fall, and produces flowers in the spring and winter, and smaller, darker flowers in the summer. The River Birch is deciduous and often grows into a multi-trunked tree. Prefers moist, acidic soils and needs to be planted in full sun.
