'Dura Heat' River Birch
(Betula nigra 'Dura Heat')
- River birch can grow 50 to 90 feet tall but is often seen 40 to 50 feet. It lacks the white trunk bark associated with other birches but is distinguished by reddish, brown bark peeling off in film-like papery curls providing interest all year round.
- It is very well-suited for planting along steam banks where it is native and in other wet areas since it tolerates low soil oxygen, flooding, and clay soil. However, this tree also does well in well-drained landscapes especially if planted in low areas and/or provided with adequate water.
- River birch is hardy and grows rapidly in full sun or partial sun/shade, but requires an acid soil (otherwise it becomes chlorotic).
- River Birches are not particularly adapted to heat but can make a nice tree if provided with irrigation and plenty of soil space. Our River Birch trees are cultivars (man-made varieties) called ‘Dura Heat’ which tolerate the heat better and retain their leaves longer into fall.
- This tree does provide a yellow fall color display, although usually of short duration.
