The Monroe Evening News is reporting that the invasive flowering rush (Butomus umbellatus) may now be established in Michigan's River Raisin. They're still awaiting confirmation on the species. The real story here, though, is that the Monroe County Drain Commissioner spotted the plant nearly three years ago, but failed in his attempt to procure an herbicide permit from the Michigan Department of Environmental Quality. Monroe County is one of seven counties in Michigan where flowering rush is known to be established. Oh well.
Thanks to Julie A. over at the Human Flower Project for sending in a link to this story.
