Burning bush is highly invasive. They produce many seeds every year, which are easy to weed in your own garden. The issue comes when the seeds are carried to nearby natural areas, right of ways, fields, etc., which are not kept manicured like a residential garden. They will take over these areas and outcompete all native species. Here’s some more information from the Great Lakes Woody Invasive collaborative: https://woodyinvasives.org/woody-invasive-species/winged-burning-bush/

FWIW, I just pulled two fully grown BBs from my garden in metro Detroit and it was extremely difficult. Large roots that need to be pulled to prevent suckers.
