Amur cork tree, an introduction from East Asia, has become a rather common weed in eastern and central Massachusetts. The tree is easily recognizable by its unusual bark pattern and rather large compound leaves. So far there is not enough data to count it invasive, though it is likely to be invasive in our state.
