I believe that this is a young Poke plant. If anyone recognizes it as something else, please tell me. If it is, Poke, or Pokeweed, or Poke Sallat, among some of it's names, is an old plant in the southern United States. It grows wild all over our property and everywhere else, along the road, in forests, etc. This picture is from my front yard. It is a plant that is very poisonous if eaten raw, but which cooked tastes a bit like a cross between asparagus and spinach. There are also folk remedy uses for the roots and berries to cure thyroid problems, rheumatism and other ailments. I am afraid to cook it myself--it must be boiled thouroughly and drained twice before eating any part. One website I went to also said the berries have a great dark red/purple stain that was probably used by Native Americans for skin and clothing. Anyway, I think it is a pretty plant, when it blooms in early spring there are little white flowers, and when very tall (up to 5 or 6 feet!) the stems turn red.
I cropped this from a picture, cutting out the bit of palmetto and some other brush around. I also increased the saturation, contrast and sharpness a bit.
