Tree Betula pendula [European White Birch] A graceful tree with beautiful white bark and pendulous branches, the European White Birch was once a common tree in many landscapes across the United States. However, the popularity of this species has decreased rapidly due to its extreme susceptibility to the birch borer. Despite its beautiful aesthetics, other birch species, such as Betula nigra (the River Birch), are recommened for use in the landscape instead.

Leaf minors especially problematic.
