I have managed to kill (unintentionally!) so many of the invasive plants listed above. Gooseneck loostrife, sweet woodruff, mint, evening primrose, vinca, lambs ears. Hard to believe, I know. Part of it is climate, the other part was lousy soil. I've been amending the soil for several years now, so I'm giving the sweet woodruff & vinca another go. They survived the past winter and are still behaving themselves, so no troubles yet. I think the worst thing I've planted is chives. I like them alot, but they seed themselves like crazy. Before I smartened up and started cutting the flowers off before they set seed I had chive seedlings everywhere!
