It's a weed. It's all over my yard. It's not a dominant or deep rooting plant, as far as I can tell. Is it useful? I've ID'd pretty much all the other stuff in my yard that I didn't put there, but this eludes me.
Most of it is pretty young. I did a bunch of earth moving this summer, and most, if not all of it has sprouted since then. Thanks in advance for your help.
Let me be really helpful by first off saying I don't know what it is.
However, the really interesting thing is that it has popped up where you did earthworks - note the absence of tap root - instead you have fine hair net roots - the sign of a "soil stabilizer" plant. How cool is that? Nature is filling a niche with the right kind of pioneer weed.
Yes....it's the little things that excite me.

Thank you for the guidance. I'm leaning toward hairy bittercress. I'll know for certain when they flower in spring, but it looks right and the description of growth patterns and preferences sounds just like what I have going on in my yard. Sounds like if I continue on the path to maturing my yard/ garden it is a 'problem' that will take care of itself.
