This little guy is a thornless blackberry. I planted it several years ago. It has struggled and I don't think it has ever produced a berry. My wife and I were planning on clearing brush and thinning a small pine stand near where we worked a couple of weeks ago, but as I passed this miserable little guy, I thought, it's time to clear the brush around the blackberry and see if it will do better. As you can see from this closeup, this is an after the brush has been cleared picture.
