Let me preface this by saying that I am NOT a gardener at all. I have a black thumb. However, we have a very large bush in our backyard that our neighbors tell us is a Rose of Sharon. It must come out of where it is because we need the space for our children's swingset. I would think something like that could be transplanted, so if anyone is interested, please send me a private message and you are welcome to have it. My hubby will even dig it up (or help if it turns out to be more than a one man operation).
Also, we have a couple of large shrubs behind our garage. I'd say they are about 6 feet high. They are probably in total about 8 feet wide. (This is several shrubs together making up that width.) They need to come out, too. Same as above -- if someone can use them and they are transplantable, you are welcome to them.
