A few years ago I began to notice a vine in my front yard landscaping with unusual little pods.. and tiny purple flowers.. I pulled it out, but it kept coming back.. and multiplying. I've learned this is Swallow Wort and is one of the most nasty invasive characters you can get. You cannot get to the roots all you can do is pull off the stems... and the roots travel and send up shoots everywhere.. Anyone have it? Anyone know how to get rid of it?
