I have a big patch of these in front of my house. There were some in the backyard too, and I finally pulled them up. My neighbor says they're a flower. I dont know. I think I had something like this year. It would be something from a seed. Is it going to bloom? What is it?
I think it is rudbeckia, Triloba.
I got some rudbeckia Tribola too and going only by the leaf it sure looks like it......if it blooms out little yellow flowers with brownish cones well you got it....more or less, well kinda.......One other thing sometimes you have one kinda leaf at the bottom of a plant near the crown and the plants have different shaped or kinds of leaves on up the stem...weird but hey Mother Nature has her reasons, I ain't arguing with her.....:)
