It looks similar to an Artemisia of some kind. Perhaps A ludoviciana.

Yep, it looks a dead ringer for albizzia. (leaves look a bit fine for mimosa pudica).

M. nyctaginia was the native I was reffering to, Just forgot the name. Nice looking, but no kaleidoscope or broken colors. Miribilis is'nt hardy in my zone, but I have one on the south side, right against the house that gets enough heat radiation in winter to make it a perrenial.

Pay attention to the information in the Carol's link regarding Datura's toxicity:" All parts of Datura plants contain dangerous levels of poison and may be fatal if ingested by humans and other animals"
