Deb - The only way that I can tell is when it starts growing. If it gets really big - then it's the one I have in my front yard. If it stays smaller - then it's the one in my backyard. LOL! The smaller is more manageable - but the bigger one definitely attracts a lot more butterflies. In fact, I haven't seen many butterflies on the smaller one. But again, I just planted it a couple months ago and it is probably just getting established in my yard. Next Spring will determine how big it may get. My larger one has very large leaves as well. Bigger flowers, too. Which is probably why the bees and butterflies like it so much. I have also heard that hummers like it, too. (I wouldn't know about that.) But it is a monster porterweed! I'll post the picture again. It is bigger now than in the picture I took several weeks ago.
