Maybe Horseweed (Conyza canadensis).
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and proclaiming...."WOW What a Ride!!" -Mark Frost

I've got the same thing I think in my front yard. It may be Forget-Me-Not if it isn't getting bigger. I vaguely remember spreading seed in that area last Spring/Summer from my plants in the backyard. If it is Myosotis it will be blooming soon.
To me it looks like one of those plants that make a big flat rosette and then send up a skinny flower stalk later in the year - or next year - usually with some sort of yellow bloom(s). No, I don't know what it actually is.
