I'm almost sure it is not a weed, but without a flower it is almost impossible to ID most plants.  It does look a lot like Stoke's aster, which does spread like this plant seems to be doing.  It also looks like a flower head may be forming.  If it comes out purplish blue, then it likely is a Stoke's aster.  If not, then wait till it flowers and ask again.  So many flowers have basel rosettes like this one, it could be a verbena, or a guara.

Question No 322342. Hoping you can now identify my plant since it is blooming 
thank you 

The unknown plant  is some type of Oenothera, or evening primrose.  There are 145 different types, so I don’t know which one.  The photo of the flower was not sharp enough to see if it had a cross-like stigma in the middle of the flower, so I had it verified today by the horticulturist at the JC Raulston Arboretum. I think it is a lovely plant.  I have included a link below that is a fun way to try and figure out plants based on categories.  For example, for this one you would select perennials, then on the next page select perennials again, select 1-3 ft., and select flower is yellow.  This narrows the field down a lot, and there is a picture for each one.  Oenothera is one of the possibilities.
