Yes, I'm also not happy about how Houzz changed the forum list around. Trying to find your forum, is like trying to find a needle in a haystack now. I have found that if you google the forum you want, you can get there faster, like if you want the Butterfly Forum, you can google gardenweb butterfly forum. Your plant looks like something in the Aster family, either Rudbeckia, or Helianthus.

Yes agree with Rudbeckia laciniata. It can spread aggressively in rich soil.

Agreed with the ID. I've got them growing between my deck and driveway in hard, dry, and poor soil for about 7 years. Performs well in that hard space but does not spread aggressively there at all. Conditions can make all the difference.

I am trying to eradicate it. It was just too happy and invading lots of space of its neighbors. it would be great in a meadow garden.
