Not something I've grown before, it looks like a peanut plant.

Thank you, Donna. I looked it up. Leaves really look like what I have. But root system... mine is like a great system underneath the surface. Main root is as thick as man's thumb, going pretty deep down. And these guys just hold on that main root in groups... you pull out one and there are more ready to come from the same spot. And it's hair roots are so invasive, they are right there where I have newly planted roses and such... and it's all in packed hard clay! Maybe I need to let it grow a little bit to check what this thing is doing actually...
