I'm pretty sure I self seeded these, but don't remember what they are. I'm guessing the yellow flowers are Black Eyed Susans.
The top flower is a Helianthus, possibly H. decapetalus. Helianthus tend to "run" underground and therefore not the greatest plants in a non-meadow garden. H. decapetalus is better behaved then most, though,
The plant is definitely NOT a Rudbeckia.
