A neighbor gave me this and said it was some sort of wildflower, but he didn't know what. It keeps getting bigger and bigger but hasn't bloomed yet. I haven't had any luck identifying it in a flower book. Does anyone know what this is?
What Is This Plant?
It looks a lot like Rudbeckia laciniata (cutleaf coneflower).
