If it's purple loosestrife, you don't want it, especially in Ohio. That is one state which has a program for total erradication of that invasive species. It's a pretty plant but will entirely take over any wetlands. For a time, it was legal to sell a "mule" version which supposedly did not produce fertile seeds. That didn't work out as that stuff also escaped into the wild. Even if you did get a stand of them started in Ohio, chances are good that an insect will come along and destroy them. That state is one of many which has imported a beetle which dines only on loosestrife. Thus you're against the wall no matter what. If the DNR officials don't come down on you, the bugs will!
