Buddleia spp.

[Toil]

aka - butterfly bush.

I am looking to make a case to have butterfly bush eradicated from a public garden bordering undeveloped area. It has been naturalized - I pulled about 8 mature plants. Uconn lists it as invasive when naturalized, rodale features an article, the brooklyn botanical lists it, the botanical review has published a paper.

Anything else? I am looking for overwhelming evidence.
