It appears to me to be some form of Chrysanthemum

Rudbeckia laciniata 'Hortensia' , aka Golden Glow.

Here is a link that might be useful: Rudbeckia

i would not leave a black pot in hot sun ... place it .. so the pot is in shade ... until it can be planted properly ... i would never plant a plant in flower ...

and i would hold it.. until it for fall planting around 9/15 .... when nights cool ...

but then i seem to be more careful than other folks about when i plant in august ...

I agree with carol.

It's a really tough plant (I grew pure laciniata), it can adapt to moist or dry places. A real survivor, but not a spreader (to me at least).

Thank you very much! I looked it up and Rudbeckia laciniata 'Hortensia' is definitely what it is. I look forward to telling my mother, she remembers these plants from her childhood. Thanks again!
