The Heritage River Birch (Betula nigra 'Heritage') is a specific cultivar of the river birch tree. River birch trees are native to the eastern United States and are known for their attractive peeling bark and tolerance to wet conditions. The Heritage cultivar is selected for certain characteristics that make it a popular choice for landscaping. Here are some key features of the Heritage River Birch:

1. Bark: One of the most distinctive features of the Heritage River Birch is its exfoliating bark. The bark peels away in thin, papery layers, revealing a range of colors from cinnamon-brown to creamy white. This feature provides visual interest throughout the year.

2. Leaves: The leaves are typically diamond-shaped and serrated at the edges. They are green in the spring and summer, turning yellow in the fall before dropping.

3. Size: Heritage River Birch is a medium to large-sized tree. It can reach heights of 40 to 50 feet with a spread of 25 to 30 feet.

4. Adaptability: River birches, including the Heritage cultivar, are known for their adaptability to a variety of soil conditions. They can tolerate wet soils and are often found along riverbanks and in low-lying areas.

5. Sunlight Requirements: Heritage River Birch generally prefers full sun to partial shade. It can tolerate a range of light conditions but tends to develop its best bark color in full sunlight.

6. Disease Resistance: River birches are relatively resistant to the bronze birch borer, a pest that can affect other birch species.

When planting a Heritage River Birch or any other river birch cultivar, it's essential to provide well-drained soil, especially if the area is prone to occasional flooding. Regular watering is important, especially during dry periods. Proper pruning can help maintain a healthy shape and remove any dead or damaged branches.
