I have several plants growing in my sweet potato beds and I have no idea what they are. We've seen them around the yard and pasture since we moved here too. The plant is short (1-2 feet) and bushy. The leaves are large and serrated. The flower are small and yellow and the seed pods look like Chinese lanterns. I haven't pulled these up because I think they're cool with all the little Chinese lanterns hanging underneath the leaves. Anyone know what this is?
