While talking with a staff member at my local nursery this morning, they said Wisteria ( sinensis) and Burning Bush (Euonymous elata) are now banned for sale in Maryland as invasive species.

I did a quick search, and here is what I came up with:

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.
Always looking for interesting plants for pollinators and food! Bonus points for highly scented plants.

@UrbanWild,

Go to Lowes or HD and get a jug of Bayer Advanced Brush Killer. Cut the wisteria vines about 2 feet from the ground. Depending on how many you have, either put them into the jug, or pour the herbicide into a bucket or other suitable container. The plants will suck it up and die. The above ground stuff will die naturally and the underground, including any runners will be killed off by the herbicide. You can also spray it onto the leaves. BUT, if you choose to spray, make sure you do it on a wind-free day and that you can control the spray. Otherwise, you'll end up killing off something else as well. I've used it successfully on both wisteria and poison ivy.
