Flowering rush (Butomus umbellatus) is on the Minnesota DNR invasive list
"Ecological Threat:

* Flowering rush is actively expanding. It has spread from a limited area around the Great Lakes and the St. Lawrence river to sporadically appear in the northern U.S. and southern Canada.
* It competes with native shoreland vegetation.
* It is a Eurasian plant that is sold commercially for use in garden pools. It is now illegal to buy, sell or possess the plant.
* There is documentation from a site in Idaho, between 1956 and 1973, where flowering rush appeared to be out-competing willows and cattails.
* Flowering rush is on the DNR Prohibited exotic species list in Minnesota."
