Invasive Species: Butterfly Bush
Buddleja davidii
While beautiful, butterfly bush forms dense thickets crowding out native plants.
It was first documented in 1939 near Eugene in Lane County.
Why is it important to control?
Butterfly bush forms dense thickets along riverbanks, crowds out native plants, and may alter soil chemistry. It reproduces by seeds with high germination rate and cut stems that can sprout roots.
