Name that Tree

If you selected Black Locust, you are correct!
You are probably wondering why the native Black Locust is not usually cultivated in its native range but is commonly used in cultivated landscapes in Europe. The problem is that the Black Locust is prone to several severe pest problems in the eastern U.S. but not in Europe. There are borers and leaf-miners, but the worst problem is infestation by the conk fungus (Phellinus robineae). It causes the tree trunks to deteriorate and fail catastrophically in windstorms, damaging cars, buildings and other nearby structures. Some extension services advise removal of Black Locusts, particularly from the sides of streets.
