These are pollinator magnets! All kinds of little flyers love them.

I have a bunch filling a 6'Lx3" W raised bed. A few escape, and are easily pulled up, and relocated on an embankment for erosion control.

I can see that someone might get annoyed if they wanted it in a certain area, and it randomly kept popping up out of boundaries, but if it's used "correctly" and given an area to itself to spread in, its boundaries can be easily maintained by a lawn mower, weed barrier, stonework, or even raised beds and walkways.

It shouldn't be planted near persons with bee sting allergies because it bustles with pollinators, including bees and wasps.

It can self seed, and individual plants pop up in various places, and that might be what they mean by invasive.

Self-sowing plants, if left there, can start new colonies, that would be hard to get rid of, especially in unmowable places.
