Help! I bought a "lemon grass" plant at my local nursery (Zone8a)and it is very purple at the bottom of the plant and looks much like a weed; not the plant s on Google image. I asked the nursery what might be going on; too little of something- too much? I am currently getting ready to pot the plant and bring it in son for the winter. Any thoughts?
