Attack someone at the garden center. LOL This actually happened to me. I was there last fall shopping for some end-of-season sales on potted perennials and day lilies (half price!), when a total stranger approached me and asked if I would like some stuff from his gardens. I thought at first he was a total wierdo. I mean, who approaches strangers and starts to offer free stuff? But as we've gotten to know him and his wife, and they are nice, kind people and have since given us lots of goodies. I also heard of people having luck putting ads in the paper when they have a garage sale, and specify plants for sale. Lots of communities have free listings for garage sales.
