Black Birch Tree
Betula nigra 'Black Star'
- With its papery peeling bark in pink and brown hues, lush green foliage and attractive yellow catkins, it's small wonder 'Black Star' ranks among our favourite ornamental trees.
- Although this birch can reach an ultimate height of 15m or so, given enough time and a can-do attitude, it's easily pruned to fit smaller gardens, too.
- The airy, spreading canopy allows lots of light to filter through, making this a perfect pick should you want to do any underplanting with perennials.
- Fully hardy and easy to grow, 'Black Star' looks fabulous incorporated as part of a woodland or woodland-edge garden scheme.
- Often also called the river birch, Betula nigra is commonly found in wetlands and swamps. It's among the only birch species, in fact, to tolerate wetter ground.
