Four states have declared this a noxious weed.

I found the species to be aggressively weedy, and I don't find it attractive enough to put in the time and energy it takes to control it while cultivating it. Getting rid of it wasn't too hard, though, through a combination of digging it out and spot-application of glyphosate herbicide.

Tanacetum vulgare is considered invasive by the Minnesota DNR
"Ecological Threat:

* Common tansy is wide spread across most northern United States and Canadian provinces.
* It is still cultivated in gardens and is common along roadsides and abandoned farmyards in northern Minnesota and along the north shore of Lake Superior. South sloping open areas are most vulnerable.
* It was introduced to the United States from Europe for medicinal and horticultural purposes.
* Common tansy is on the MDA Secondary noxious weeds list in Minnesota."
