This isn’t really a flower, but it’s an autumnal plant growing along the shore of our West Lake, where plants are just left to grow wild. I don’t know the name of it either, but when I spotted it, I stopped to examine it, and finding it interesting, I photographed it! It has a seed pod that resembles a pine cone growing on it.

If anyone can tell me the name of this plant, I’d appreciate it!
