I did a lot of image searching tonight and can't find any alternathera, perilla, iresine or plectranthus that really match it. I'm leaning towards plecthanthus. Going to go take a photo of the plant in the container one of these days and will watch to see if it blooms. The planter is outside a building near where I work. I stuck the cutting in soil and will try to get a little one to try rooting it in water. Looks very nice with the coleus. It has a little more thickness to the leaf than most coleus or perillas I've seen.
