Betula nigra--River Birch, Red Birch
Hardiness Zones: 3 to 9
Height: 45 ft
Spread: 35 ft
Type: deciduous tree
Annual Growth Rate: more than 18 inches
Comments: River Birch has beautiful, peeling, brown bark that reveals camel-colored
and pink beneath. It is more borer resistant than white bark
birches, which makes it a much longer-lived landscape tree. Iron chlorosis may be a problem if the pH is too high.
The tree tolerates a range of soil moisture but is especially well suited for wet soils.
The soft outline, and reddish, scaly bark provides summer and winter
interest in both multistem ("clump") and single stem
forms. The fall color is yellow.
'Cully' (Heritage(R))(PP4409) - The lighter colored bark consists of patches of cream, orange and pinkish-tan.
