As the owner of eight separate ponds, I regard this as a beautiful
plant which attracts countless myriads of insects and provides nectar
for most of them.

May be God intended it was "invasive" and maybe you lot know better,
in your organised fashion?

The most invasive things I have discovered in my lifetime are people,
not plants. I also believe that people do far more damage than
plants, even IF plants are invasive.

Kind regards,
