Definitely a young stinging nettle, aka itchweed. Make sure to wear gloves if pulling it out by hand! The bigger the plant gets, the pickier and more toxic it is. Causes painful bumps on skin.
I agree with many on here - it looks like geranium (not related to the bright colored flowering plant usually grown as an annual). For photos to compare your plant http://www.robsplants.com/plants/geranium.ph...
I believe, like Gail K. that it's perennial geranium, cranesbill. I have several patches of it and love it. It blooms for a long time and brings a spot of color to a dark corner. It'll grow on the north side of the house.
Looks like the herb Feverfew....used in the old days to treat fevers. Blooms with mini daisy looking flowers. A great filler in flower arrangements!!!!!
It's a native, wild plant in the celery family. Get's really tall with a purplish hollow stem but doesn't flower. It does resemble Tansy, hardy geranium or Feverfew when small like this. It is attractive but be sure to cut it down before it spreads it's seeds.
Our garden club's meeting last night was on Herbs & I'm now positive of my previous description. It's called Lovage & is a native plant in the parsley family in my area.

I grow lovage and mine does not look like this. One way to tell would be to smell the leaves. Lovage has a strong celery scent and flavor and grows about 6' tall.
