The pods open up into beautiful, delicate, poppy-like flowers. Anyone know what it is? Thanks a lot.

Answer 1

Check the sites below for lots of info on your plant:

Hibiscus trionum

Answer 2

Looks like Venice Mallow to me.

I get that here and there myself.  Sometimes I let it be, especially if I don't have anything to plant right there.  It's not awful looking, and although weedy, it's not crazy invasive or anything.  When I want it out, I pull it easily, and it complies.
