Friend or foe?
This plant has been happily growing this summer next to my stairs but I cannot figure out what it is. It doesn't seem to be getting any taller (about 8 inches high currently), but it is getting fuller. When it was small, I swore it was a volunteer tomato plant, but now I know it isn't. Any ideas? The stem is thick like a succulent, and the leaves have very little distinctive smell. No flowers...just happy, healthy stems.
