I can attest to burning bush & wisteria invasiveness. Have had several projects aimed at eradicating them and restoring habitat areas. When we bought our current house, I immediately terminated two burning bushes and for 3 months have been trying to kill the wisteria and porcelainberry. In fact, this morning I was ripping out new sprouts once again.
I know a lot of folks love them...and they are pretty. A lot of folks think if they have not seen them pop up in other places in their yard that they are not invasive or they can be controlled. Not only is that an illusion, there is great expense in time and money to eradicate and what it does to a lot of natural plant communities cascades into animal communities. I have never understood how a lot of these plants can still be sold. BTW, Tier 2 restrictions basically don't amount to much if all one needs is a sign.
