I have lived in Northern VA
I have lived in Northern VA and now live in the eastern panhandle of WV and have yet to see my butterfly bushes propagate in the 20 years that I have had them. Honeysuckle, the vine, on the other hand is very invasive. Have not noticed that about the honeysuckle bush. Here, I would call milkweed and thistles invasive as well as mimosa trees.
