General Description

Dura-heat river birch is a handsome, often multi-stemmed, fast growing tree that is native to the southeastern and central United States. Its most notable ornamental feature is beautiful peeling bark that appears in mixed shades of salmon to cinnamon exposing a creamy-white inner bark. Dura-Heat ('Bnmtf') river birch has a pyramidal shape, dark green, diamond-shaped, double-toothed leaves and is quite heat tolerant. Dura-Heat is a bit more compact than other river birches but still matures to a medium or large height. It has elongated flowering catkins (drooping flower stalks) which appear in spring. Small cones with winged seeds appear late in the summer and fall. Its medium-green leaves turn a dirty yellow in the fall.

Dura-Heat river birch is a good choice for wet sites, hence its name, but can tolerate locations with drier soils that are not alkaline. This species is resistant to birch borers and a good choice for using in mass in lawns and public spaces. River birch has a tendency to drop many fine branches on the ground, especially after storms.
