Looks like ground elder to me. The roots are very invasive and the only real ways to control it are to either dig out the roots completely (almost impossible as any little bit left will regenerate) or to use a herbicide.
No doubt some will say leave it alone or that you can eat it, but having had to deal with this in my own garden I would urge you to srongly consider spraying the whole area with glyphosate based weedkiller in late spring and repeating as necessary.
