It looks a lot like goutweed (Aegopodium podagraria), which is edible. Go back and look closely at the leaves. See how the stem separates the leaf into three segments? Some of the segments should have three fully divided leaflets, other's will just have lobes and still be fused at the bases. This is a giveaway for this plant as far as I know. Of course, you are messing with carrot/parsley family plants, some of which are extremely toxic. Do some further research using this info as a springboard (you may want to dig a plant up and observe how the roots grow or wait for a flower) and if you decide to eat some, go very light the first time.
