That's exactly what it looks like, turnip greens; is there any sign of a "turnip" bulb? Compare to the pix located here:

Certainly a Brassica of some description. Is it located in arable land? You sometimes get weeds like this in fields that have formerly grown Canola.

Thank you both for the replies, this soil is what I would think is of poor quality alongside a hill that was bulldozed to improve a personal driveway facing east, both the newly exposed earth and the fill scraped off the surface used for fill below the driveway grew these plants, I immediately spread some "highway mix" seed to grow on the new surfaces but the dry summer seemed to allow these things to grow best, I believe these blew in and not part of the mix. There are so far no blooms and no bulb but sort of a carrot looking root difficult to pull out which I don't have a picture of.

Maybe rutbaga? The leaves look too smooth for turnip to me. Was it farmland before the houses were there? Scraping the soil could bring old seed to the surface.

I suppose it could be rutbaga, this land was used for farming many years back and I'm not sure what was grown there however a neighbor about one half mile away had some excavating done for his new house and the same type of plants have grown there too, I was thinking someone else might have had these growing too under similar circumstances and know just what they are, I hope by next summer we receive more moisture so grass and wildflowers can grow.
