Chamaecrista fasciculata, formerly Cassia.

I think that's it. Thank you so much.

I moved a Partridge Pea to a new location, and it dealt with transplant shock buy closing it's leaves during the hot times of the day. It self seeds everywhere. Just like Verbena bonariensis, once you grow it, it's with you forever. It's a new place, and the landscape plants were from the previous owner. Not my style at all. I detest privets and I absolutely loathe Stella de oro daylillies with a passion! Still in the process of ripping out all the landscape fabric in this area and the lone pea makes me happy. Ground ivy vs crabgrass, who will be the victor? lol
