Funny you should mention that. My neighbor's wife passed away some years ago and had magnificent gardens. I have been allowed to go over there and take whatever I want. Last summer I took quite a few plants. They all came with other stuff that was either in bulb form or dormant things. You see everything there has just grown together in one big mess. Well, I was over there just this past weekend and was delighted so see Virginia Bluebells all over. So it could possibly be that. In addition I saw plants coming up that look just like this picture. So whatever it is I think it is a safe bet that is came from those gardens!
